blister beetle larvae

University of Kentucky Entomology. Blister beetles pose a potential threat if horse owners use alfalfa as a source of hay. Meloe franciscanus is a species of blister beetle in the family Meloidae. Gerardia (Scrophulariaceae). Damage: The larvae of the blister beetles destroys grasshopper egg pods. When blister beetle larvae do their little kids-in-a-trench-coat ruse on the sands of California’s Mojave Desert, they always crawl up at least 11 inches on their grass stalks. Blister beetles have fascinating interactions with other insects. The abdomen becomes more robust, with indistinct segments, and later stages do not feed. Their larvae emit chemicals that smell like a female bee to a male bee. Adult blister beetles are categorized into many different species and depending upon the particular species, they eat plant leaves, parts of flowers, pollen and plant nectar, plus some blister beetle larvae consume grasshopper eggs and feed on immature bees. Adult Blister Beetles can be found on apple trees and other similar plants. The adults sometime… May-June. Rare. Figure 3: These are the most common alfalfa products fed to horses: baled (Top), cubed (lower left) or pelleted (lower right). Kinney KK, Peairs FB, Swinker AM. Florida has 26 species, only a small fraction of the total number in the U.S., but nearly three times that of the West Indies (Selander and Bouseman 1960). In small gardens, it may be sufficient simply to pick the beetles from the plants. Figure 7. Blister beetle larvae are parsitoids, and although the larvae of some species prey upon grasshopper eggs, the larvae of most species target and consume the egg or larvae–and/or accompanying provisions–of solitary ground-nesting bees (bees in the families … Tetraonyx quadrimaculata (Fabricius) - Trinidad, Lesser Antilles, Puerto Rico, Hispañola, and Not common. Most beetle larvae molt at least three times before transforming into pupae. Eggs are laid near but not necessarily on the food source of the larvae. P. mutata (Gemminger) - Northern Florida, including the panhandle, south to Polk County. E. vittata (Fabricius) - the striped blister beetle. Blister beetles (Meloidae) are commonly confused with beetles in the family Oedemeridae (false blister beetles) (Arnett 2008) and the Tenebrionidae subfamily Lagriinae (long-jointed beetles). Adults of most of the Florida species are described by Enns and Werner (Enns 1956, Werner 1945). When squeezed, blister beetles exude an irritating, oily chemical that can blister one’s skin. Taken internally or absorbed through the skin, cantharidin is highly toxic to mammals. Photograph by Lyle J. Buss, University of Florida. There is an extensive literature dealing with its reputed aphrodisiacal properties and numerous reports of human poisonings, both accidental and deliberate. Figure 1. Hypermetamorphosis is common among blister beetles. 2001. The wing covers are rounded curved around the body (not flattened). The egg, attached to flowers (or somewhere else where a bee will visit), hatches into an active larva called a triungulin, with well-developed legs, antennae, and the wherewithal to grab onto a visiting bee. In the following list, seasonal distribution is not mentioned for species that are active in the adult stage from spring to late summer or early fall. Of the Florida species, Nemognatha punctulata LeConte (misidentified as Zonitis vittigera (LeConte)) has been found in a nest of a Megachile sp. Keys to genera for adult beetles (Arnett 1960) and triungulin larvae (MacSwain 1956) are given in references. Just like other bugs, blister beetles have a life cycle that involves different stages (called metamorphosis). Convolvulaceae (Ipomoea) and Leguminosae (Bradburya, Coelosia) in the U.S. and these families and Bignoniaceae, Euphorbiaceae, and Verbenaceae in the West Indies. However, except for first instar larvae (triungulins) frequenting flowers or clinging to adult bees, larval blister beetles are seldom seen. Three major color forms: gray tinged with blackish, margined (black with ash gray margins), and black. General handling of adults seldom results in blistering unless the hemolymph contacts the relatively thin skin between the fingers. August-October. Journal of Dermatological Treatment 20: 114-119. California Medicine 93 11-12. Poisonings have been traced to several species. Selander RB, Bouseman JK. As tiny larvae, they must hitch a ride to the right kind of bee’s nest, then parasitize it until mature. Most adults eat only floral parts, but some, particularly those of Epicautasp… 1. They undergo several changes during their lifespan from birth to adulthood. ing from eggs, the highly mobile blister beetle larvae seek out and feed on grasshopper eggs. Photograph by Lyle J. Buss, University of Florida. Adult bronze blister beetle, Lytta polita Say. 1956. and J.G. Figure 16. Kirk VM. Adult blister beetles are categorized into many different species and depending upon the particular species, they eat plant leaves, parts of flowers, pollen and plant nectar, plus some blister beetle larvae consume grasshopper eggs and feed on immature bees. In Meloinae, the fully fed FG larva generally excavates a chamber apart from the feeding site. Cicuta, Daucus, Eryngium, and several other Umbelliferae. Research is available to indicate the amount of cantharidin levels present in common species, as well as the estimated number of beetles necessary to provide a lethal dose to horses (Kinney et al. (March 2006). The cantharidin that causes skin to blister is used to make medicine for removing warts. St. Johns, and Volusia counties) and Myrtle Beach, South Carolina (Kirk 1969). Catholic University Press, Washington, D.C. 1112 pp. February-May. Photograph by Samuel Grubb. Photograph by Lyle J. Buss, University of Florida. The Taxonomy of North American. In most areas, the beetle will produce one to two generations each year. This is why blister beetle numbers increase dramatically following high grasshopper populations. Since adults are gregarious and often highly colored, they tend to be conspicuous. A few larvae evidently prey on the eggs of blister beetles (Selander 1981). The name blister refers to the chemical cantharidin in their bodies. For this reason, this type of metamorphosis is referred to as hypermetamorphosis. A classification of the First Instar Larvae of the Meloidae (Coleoptera). Recorded in Florida only from the Keys and Dade County. The family Meloidae, the blister beetles, contains about 2500 species, divided among 120 genera and four subfamilies (Bologna and Pinto 2001). Adults are active during the summer and at this time can be found in alfalfa. Others spend more time on the ground, laying eggs in the soil. Several alternative developmental pathways have been identified. Blister beetles. The biology of blister beetles of the Vittata Group of the genus. She lays her eggs in soil. Figure 18. Blister beetle larvae form a cluster on the end of a piece of grass to mimic a female bee. Proceedings of the National Academy of Sciences, 103, 14039–14044. Recorded from coastal, southeastern North Carolina. Adult Epicauta floridensis Werner (left), and E. cinerea Forster (right). This fact sheet describes the life cycle and habits of the blister beetle, highlighting its importance to agriculture. Certain blister beetle larvae, including scavengers in bee nests and ectoparasites or endoparasites of other insects, are hypermetamorphic. Attracted to lights. Not common. Blister beetles have evolved in a unique way. Adult Blister Beetles can be found on apple trees and other similar plants. Figure 6. A revision of the genus. 1938. Systematic Entomology 26: 33-72. Through autumn and winter, maturing larvae become less mobile and more grub-like in appearance, and they develop a big- The newly hatched blister beetle larva (known as a triungulin) is tiny, but highly active and burrows into the soil. Enns WR. Figure 4. Crop damage caused by adult margined blister beetles, Epicauta pestifera Werner. Figure 10. the U.S. Coastal Plain from northern Florida (Alachua and Putnam counties) to Alabama and North Carolina. Evidence for a third type of larval prey in blister beetles (Coleoptera: Meloidae). The larvae are insectivorous, mainly attacking bees, though a few feed on grasshopper eggs. And if the bee happens to be a male, they wait to further transfer themselves on the body of a female bee. The family Meloidae, the blister beetles, contains about 2500 species, divided among 120 genera and four subfamilies (Bologna and Pinto 2001). Adult hosts: Ilex (Aquifoliaceae), Sapindus (Sapindaceae), and Albizzia, Amorpha, and Robinia (Leguminosae). Cirsium and Tetraognotheca (Asteraceae). They attach themselves to the body of the bee. The larvae of some … The head and appendages of the second through fifth instars become reduced in size with each molt. A key to Epicauta species is in Pinto (1991). But at least one species, for example, focuses on flowers of apple, plum, and other rose-family trees. Journal of the Kansas Entomological Society 54: 757-783. Eggs are laid in masses in the ground or under stones (Meloinae) or on the food plants of adults (Nemognathinae). In this phase the musculature undergoes profound degeneration and respiration is reduced to an extremely low level, permitting survival for more than a year, if necessary. Eastern U.S., west to Texas and South Dakota and north to Massachusetts. Blister beetles have unusual larvae. Body length 16mm The beetle is bright orange colour with black patch patterns. April-May. the main food source for the blister beetle larvae. Black blister beetle. E. heterodera Horn - Southeastern U.S., coastal Mississippi to Georgia and south in Florida to Osceola County. After completion of lar-val and pupal development in the spring, adults emerge. Hand-Picking Northern Florida, including the panhandle, south to Indian River County Adult hosts: Many Leguminosae and Solanaceae, including alfalfa, beet, eggplant, potato, soybean, sugar beet, and tomato. 1979. After finding the eggmass, blister beetle larvae become immobile and spend the rest of their developmental time as legless grubs. Adults commonly live three months or more. Heavy infestations often occur during or just following a grasshopper outbreak. Blister beetles receive their common name from the ability of their hemolymph to produce blistering on contact with human skin. Wear gloves to protect the skin. Transformations of blister beetle larvae. P. lineata (Olivier) - Northern Florida, including the panhandle, south to Polk County. Also known as The Oil Beetle as they exude oily droplets from their joints if disturbed. Posts about blister beetle written by ameshollowfarm8681. Adult Pyrota lineata (Olivier) a blister beetle. Figure 8. Note: According to the book Beetles of Eastern North America by Arthur V. Evans: “Adults on flowers of palmetto (Sabal palmetto), New Jersey tea (Ceanothus americanum), aster (Seriocarpus), etc.” Additional images are available on BugGuide. Blister Beetle Biology They emerge from the eggs as active campodeiform larvae, then molt into eruciform and scarabaeiform stages. Most distributions and some host data are from Piinto (1991). The larvae of blister beetles climb onto bees and hitch a ride to the bees’ nests where they proceed to eat the eggs and stored food. Through autumn and winter, maturing larvae become less mobile and more grub-like in appearance, and they develop a big- ger appetite for grasshopper eggs. Since grasshoppers are pesky too, blister beetle is a bit of a beneficial insect for the garden. The larvae of blister beetles climb onto bees and hitch a ride to the bees’ nests where they proceed to eat the eggs and stored food. The black blister beetle adults are largely pollen feeders, but they also feed on alfalfa blossoms. Young larvae of other blister beetles lurk in flowers. A few adults are nocturnal, but most are diurnal or show no distinct diel cycle. During the time they are larvae, blister beetles climb up flower stems and wait for the arrival of … High pressure liquid chromatographic determination of cantharidin, using a derivatization method in specimens from animals acutely poisoned by ingestion of blister beetles, Sansome D. (May 2002). Ed. encapsulated by the cast but intact skins of the last instar FG larva and the C larva. The Black Blister Beetle (Figure 5) has a preference for alfalfa, and the Striped Blister Beetle (Figure 2) can occasionally form large mating aggregations that can result in a high concentration of beetles in some hay bales. Similar Images . The larvae of the common blister beetles are beneficial, since they destroy grasshopper egg pods. Adult female Epicauta heterodera Horn, a blister beetle. Also taken on Amaranthus, and Cynachum nigrum (L.). 1979. Represented in Florida, where it occurs south to Highlands County, by the nominate, eastern race. Eggs are laid near but not necessarily on the food source of the larvae. Phylogenetic studies of Meloidae (Coleoptera), with emphasis on the evolution of phorsey. Blister beetles in the genus Meloe are called oil beetles because of a yellowish oil they excrete from their joints when squeezed or distressed. Proper identification of blister beetles in regards to various other kinds of non-toxic beetles that might resemble them, such as the asparagus beetle, is important to protecting livestock and preventing crop damage.There are some 250 kinds of blister beetles, members of the family Meloidae, spread across the U.S. MacKay RJ, Wollenman P. 1981. Photograph by Sean McCann. Adult clematis blister beetle, Epicauta cinerea Forster, margined color form. Management. !ere they hitch rides on visiting bees and are carried back to nests where they can feed on bee eggs and stored food. Some species specialize in eating grasshopper eggs, and for this reason, are considered beneficial insects. Adults visit flowers to eat nectar, pollen, and sometimes entire flowers. It is widely assumed that cantharidin confers chemical protection from predators, but there is little evidence for this. Blister beetle larvae only eat grasshopper eggs, but you can find adult blister beetles munching on flowers like amaranth, dandelions, sunflowers, chrysanthemums, alfalfa and acacia, in addition to their preferred source of grasshoppers. Blister beetle larvae only eat grasshopper eggs, but you can find adult blister beetles munching on flowers like amaranth, dandelions, sunflowers, chrysanthemums, alfalfa and acacia, in addition to their preferred source of grasshoppers. Adults are active during the summer and at this time can be found in alfalfa. Because of the beetles' gregarious behavior, their attacks can be locally catastrophic. Several of the Florida blister beetles feed on cultivated plants. Larval development is hypermetamorphic, with four distinct phases. Figure 9. After hatch-ing from eggs, the highly mobile blister beetle larvae seek out and feed on grasshopper eggs. Northern Florida, including the panhandle, south to Highlands County. Blister-beetle larvae develop by hypermetamorphosis: Each growth stage, or instar, is different in appearance and habits. In particular, when you find them mating in clusters, that’s the easiest time to take action in the home garden. Eggs hatch in about 12 days, develop into active larvae and quickly start searching for grasshopper egg pods buried in the soil. The larvae overwinter in the soil in a specialized form. While uncomfortable, no medical treatment was implemented and the blisters soon diminished on their own. Adult Blister Beetles can be found on apple trees and other similar plants. Orange Blister Beetle - Zonitis sp. They are also known to … Phoretic nest parasites use sexual deception to obtain transport to their host's nest. The first-stage larvae of many species of Epicautaare active, long-legged insects (called triungulin larvae) that forage for grasshopper eggs. Has been taken in large numbers at lights. Blister beetle eggs are usually laid in the soil during summer. Blister beetles are found throughout Canada and the United States. Adult beetles are phytophagous, feeding especially on plants in the families Amaranthaceae, Asteraceae, Leguminosae, and Solanaceae. This page contains information and pictures about Orange Blister Beetles that we found in the Brisbane area, Queensland, Australia. 1981. Representative Genera and Species: Epicauta pennsylvanica Pollinator Life Cycle: A complete life cycle can take from 30 days to three years. Finding blister beetle eggs or identifying them in their larval stage is extremely difficult. P. schaefferi ((Blatchley) - A taxonomically isolated species known only from Florida (Pinellas, Blister beetles are ‘hypermetamorphic’ – a kind of complete metamorphosis in which the different larval instars represent two or more different forms of larva. Adult hosts: recorded from grass. 1979). Figure 11. N. piazata Fabricius - Represented in Florida by the nominate race (Mississippi to West Virginia south), which occurs statewide, including the Keys. More than 400 species in North America north of Mexico. Typical blister beetle with distinct narrow neck, long, soft wing covers and tip of abdomen showing. Photograph by James Castner, University of Florida. Rare. When development resumes the muscles regenerate and, through ecdysis, the larva once again becomes scarabaeiform (second grub phase, SG); at this point it may or may not excavate a pupal chamber. The female beetle doesn’t produce cantharidin so she receives small amounts when she mates. Adult hosts: Wide variety of plants, including many Asteraceae, and such crops as alfalfa, beet, and potato. Blister beetles have unusual larvae. They are a flghtless Beetle. A list of the beetles of South Carolina. Common. Horses have died from eating hay containing dead blister beetles. Eastern North America from Atlantic coast west to the Great Plains, southern Canada south to Texas and the Gulf Coast. and Alachua counties to Hillsborough County. Blister-beetle larvae develop by hypermetamorphosis: Each growth stage, or instar, is different in appearance and habits. After completion of lar-val and pupal development in the spring, adults emerge. Adult "Florida" blister beetle, Epicauta floridensis Werner. At lights. When a male shows up ready to mate, the larvae … The larvae of some Meloinae, including most Epicauta spp., prey on the eggs of acridid grasshoppers. Entomology Volume 12. Secreted by blister.. Vector . In the first instar or triungulin (T) phase, the larva reaches its feeding site on its own (most Meloinae) or attaches to an adult bee and is carried there (Meloini (not in Florida) and Nemognathinae). Millar. Photograph by James Castner, University of Florida. Figure 12. In general, summaries of food plants do not pertain exclusively to Florida. A blister beetle's life cycle is like that of most other beetles—for the most part. 1960. To be specific, some of the most common plants that they eat and damage include eggplants , squash, peas, cabbage, carrots , potatoes, tomatoes , alfalfa, beet, and melons. The pronotum (just behind the head) is narrower than the head and the rest of the body. Numerous Asteraceae and Psoralea (Leguminosae). Blister beetles go through several larval stages, the first of which is typically a mobile triungulin, the first instar larvae in … Upon finding an egg pod it then molts to a sedentary, grub-like form that begins to feed on the eggs. Figure 17. The head and appendages of the second through fifth instars become reduced in size with each molt. They then release a volatile substance similar to the pheromones emitted by a female bee, which attracts a male digger bee. There then follow a series of Recorded cantharidin content of adult beetles (by dry weight) ranges from less than 1% to a high of 5.4%. The earliest stage, though tiny, is active; at this point, they have large heads and slender bodies, with functioning legs. Adult blister beetles are often seen visiting flowers for food and mating opportunities. Adults are soft-bodied, long-legged beetles with the head deflexed, fully exposed, and abruptly constricted behind to form an unusually narrow neck, the pronotum is much narrower at the anterior end than the posterior and not carinate (keeled) laterally, the forecoxal cavities open behind, and (in all Florida species) each of the tarsal claws cleft into two blades. We facilitate and provide opportunity for all citizens to use, enjoy, and learn about these resources. In Florida, recorded in Alachua and Orange counties. Nemognatha nemorensis Hentz - North Florida, south to Pinellas and Brevard counties. The bee unknowingly carries it to its nest, where the larva molts and becomes a pudgy, sedentary grub that eats the honey, eggs, and/or larvae of the host bee, then pupates and becomes an adult blister beetle. Blister beetle eggs are usually laid in the soil during summer. This bee mistakes the ball of larvae for a female digger bee, and attempts to mate with it. Female blister beetles deposit clusters of eggs in the soil in late summer. Some species eat leaves. Larvae jump onto a passing bee, stowaway to the bee's lair, and then feed on bee eggs and bee larvae inside. In some species that prey on bees the FG larva uses only a single cell, while in others it digs into nearby cells and devours their contents. Adult hosts: Ipomoea (Convolvulaceae), Schrankia (Leguminosae), and (in captivity) Solanum (Solanaceae). Blisters commonly occur on the neck and arms, as the result of exposure to adult beetles attracted to outdoor lights at night. When they hatch the larvae search in cracks in the earth for Grasshopper egg pods. P. sinuata (Olivier) - Coastal Plain from Mississippi to North Carolina; south in Florida to Highlands County. blister beetles lay eggs in areas of rangeland that may serve as breeding grounds for grasshoppers. Blister beetle eggs are usually laid in the soil during summer. Photograph by Lyle J. Buss, University of Florida. Subfamily Cicindelinae (about 100 species in North America), About 2,400 species in North America north of Mexico, Nearly 500 species in North America north of Mexico, Lady Beetles (Ladybird Beetles; Ladybugs), Wildflowers, Grasses and Other Nonwoody Plants. Adult beetles are phytophagous, feeding especially on plants in the families Amaranthaceae, Asteraceae, Fabaceae, and Solanaceae. Proceedings of the U.S. National Musuem 111: 197-226. The larvae of other blister beetles parasitize bees, limiting populations of pollinators. The larvae are parasites of bee larvae, eating them and … While sometimes considered parasitoids, in general, the meloid larva apparently consumes the immature host along with its provisions, and can often survive on the provisions alone; thus it is not an obligatory parasitoid, but rather a facultative parasitoid, or simply a kleptoparasite. A third, weaker faunal link with the West Indies is represented by Pseudozonitis longicornis (Horn), which belongs to a group including one West Indian species and two relictual species in east Texas (Enns 1956, Selander and Bouseman 1960). Zonitis vittigera (LeConte) - Eastern U.S. and southeastern Canada. She lays her eggs in soil. Lytta polita Say - the bronze blister beetle. Southern Canada from Alberta to the Atlantic Coast south, throughout much of the United States, but not the Pacific Coast states, to northern Mexico. The family Meloidae, the blister beetles, contains about 2500 species, divided among 120 genera and four subfamilies (Bologna and Pinto 2001). Whether they feed on grasshopper egg pods or infest bee nests, older blister beetle larvae become increasingly sedentary as they molt and mature (… There may be as many as 10 million species of insects alive on earth today, and they probably constitute more than 90 percent all animal species. Adult hosts: Helenium and other Asteraceae. FIGURE 1. The following summer they transform into the pupal stage and soon emerge in the adult stage. Blister beetles are unusual in their life history. Once egg pods are found, blister beetle larvae cease searching and begin to feed. After feeding to repletion, the larva, through ecdysis, becomes scarabaeiform and enters a period of rapid growth (first grub phase, FG) that lasts until the end of instar five or six. Adult hosts: Wide variety of plants, including Amaranthaceae (Amaranthus), Solanaceae (Solanum)and Fabaceae (Medicago, alfalfa), and such crops as bean, beet, cotton, potato, and tomato. Young larvae of other blister beetles lurk in flowers. April-June. Blister beetles have one generation per year. Adult hosts: unknown. Photograph by Lyle J. Buss, University of Florida. Females typically mate and oviposit periodically throughout their adult lives. First instar larvae are highly mobile and seek out their food sources. Saul-Gershenz, L.S. Adult Epicauta pensylvanica (De Geer), the black blister beetle. N. punctulata LeConte - Bahama and Cayman islands, Cuba, Jamaica, and the southeastern U.S. Invertebrates are animals without backbones, including earthworms, slugs, snails, and arthropods. 2006, Mackay and Wollenman 1981, Schoeb and Panciera 1979) have revived interest in the pathology of cantharidin toxicosis and led to the development of a highly sensitive technique for detection of the compound (Ray et al. In both groups, the body is navicular (boat-shaped) and heavily sclerotized and there is a definite pattern of setation. In this sense, blister beetles can be considered a beneficial insect, but only in the larval stage. Body length generally ranges between 3/4 and 2 cm in the Florida species. Consequently, alfalfa grown near rangeland has a greater likelihood of blister beetle infestation. Two species occur both in the southeastern U.S. and the West Indies. Infestations often occur during or just following a grasshopper outbreak. Different types of blister beetles prefer different plant families; most prevalent are plants in the sunflower, bean, and potato families. We protect and manage the fish, forest, and wildlife of the state. Blister beetle larvae devour clusters of eggs, then overwinter in the soil and emerge as adults in late spring or early summer. September-October. South Carolina Agricultural Experiment Station Technical Bulletin 1033: 1-124. Sheep field, October 21, 2011. After the Blister Beetle pupates, it makes its way out of the lair. Threestriped Blister Beetle Adult (Raymond Cloyd, KSU) In general, adults are present from May through October. Biological synthesis and function have been largely neglected. They are a flghtless Beetle. A revision of the genera. Kartal Durmazlar SP, Atacan D, Eskioglu F. 2009. Some beetles can eat both plants and animals, while others eat just one type of food. Zonitis cribricollis (LeConte) - Widely distributed in Florida, south to Dade County Achillea, Coreopsis, Helianthus, and Rudbeckia (Asteraceae). The larvae are parasites to solitary bees like the Augochlora Sweat Bee. Nemognatha plazata Fabricius, first instar larva. Figure 14. Figure 15. Eastern North America, from eastern Canada to the Gulf of Mexico, less common west of the Mississipii. Also, most of their hosts are agricultural plants. Meloid beetles (Coleoptera) of the West Indies. During the time they are larvae, blister beetles climb up flower stems and wait for the arrival of a bee. When blister beetle larvae do their little kids-in-a-trench-coat ruse on the sands of California’s Mojave Desert, they always crawl up at least 11 inches on their grass stalks. The beetle larvae emerge from the ground in a group, ascend vegetation one after the other and form themselves into a compact ball in an elevated location. Georgia border south to Charlotte and Highlands counties. E. obesa (Chevrolat) - Southeastern Canada, south through eastern U.S., south to Veracruz and Oaxaca, Mexico. E. torsa (LeConte) - Oklahoma and east Texas, east on the Coastal Plain to Georgia and north to Pigweed, goldenrod, goathead, puncturevine, peanuts, soybeans, and many other plants also serve as hosts for these beetles. Photograph by James Castner, University of Florida. Probably statewide in Florida. Pseudozonitis longicornis (Horn) - Kansas and east Texas east along the Coastal Plain to South The blisters soon diminished on their own. Epstein J, Epstein W. 1960. Blister beetles also do damage to grasshoppers, one of the most destructive farm and garden pests. 1945. Blister beetle larvae have unusual feeding habits. The blistering on the individual shown in the photograph, while uncomfortable, was not painful. Adult hosts: Asteraceae, Schrankia (Leguminosae), Asteraceae, and cotton. Photograph by John L. Capinera, University of Florida. It is found in the deserts of the southwestern United States. Carolina; recorded in Florida from Highlands County south to the Keys. E. fabricii (LeConte) - the ashgray blister beetle. So far as known, all larvae are specialized predators. Nemognathine larvae are distinctive in having one to two (not four to five) stemmata on each side of the head, an ecdysial line on the thorax, and no pulvilli (bladderlike appendages). 1979. This oil contains cantharidin, an irritating chemical that can cause blistering in many people.
