The upper surface of the forewings is black with a narrow marginal row and a broader sub-marginal row of light yellowish spots. The spicebush swallowtail butterfly caterpillar also has two pairs of false eyes to frighten away predators. They are a whitish/greenish color. Most of these caterpillars have devised a mechanism to store the toxins from the leaves of the plants they eat in glands that are present under their skin. Figure 10. 2000). This is a cool caterpillar with fake snake eyes. West DA, Hazel WN. 1993. Photograph by Donald W. Hall, Entomology and Nematology Department, University of Florida. Considering the thick outer coat of a dog, chances of these skin allergies are very less. Right: fifth instar. The long proboscis of spicebush swallowtail adults allow them to feed at tubular flowers that are not accessible to many butterflies (Opler and Krizek 1984). The median areas of the hind wings are dusted with blue in females (Figure 3) and blue-green to green in males (Figure 4). Yeah, caterpillars can be poisonous to dogs. Because if they were harmless as they look, they would have been an easy snack to most predators. Borror DJ. I still remember the first time I discovered one of these charismatic caterpillars in the wild. Distribution maps for the three species can be found at the Plants National Database. Photograph by Donald W. Hall, Entomology and Nematology Department, University of Florida. Common symptoms include burning sensation followed by an itching sensation, and these can eventually develop into skin rashes if left untreated. Pupation is usually near the ground on slender stems among leaves (West and Hazel 1996). More commonly, they are extracting minerals from wet soil, not from puddles (Marc Minno personal communication). Journal of Insect Behavior 5: 547-553. Your earlier instar can be compared to this image on BugGuide.. They also drop red drops of liquid when threatened. If you closely observe a caterpillar, you can see the pointed spines that lay hidden under their hairs. If you are not sure about a caterpillar, it is best to stay away from them! Younger larvae (instars 1-4) are bird-dropping (or lizard-dropping) mimics (Figure 7). No, the black fuzzy caterpillars aren’t poisonous, but they do sting. Naturegraph Publishers. As the name suggests, the spotted oleander caterpillars are commonly found on the leaves of the oleander shrubs. Many creatures are predators of the spicebush swallowtail. The leaf shelters constructed by developing larvae likely provide some protection for all larval instars. Once known as Green-Clouded Swallowtails, males of the species were aptly named. Deering MD, Haslitt T, Scriber JM. These caterpillars are known as the most destructive pest species to the pine and cedar trees in Central Asia & North African forests. They do so because most of these caterpillars are poisonous! Wagner DL. Among all the techniques, our interest lies in those caterpillars that are venomous. Gainesville, Florida. 117-131. b) Hyla squirella Bosc. These include birds, spiders, robber flies, and dragonflies. Princeton, New Jersey. Photograph by Donald W. Hall, Entomology and Nematology Department, University of Florida. Photographs by Donald W. Hall, Entomology and Nematology Department, University of Florida. One of the more unusual features of this caterpillar is its fake eyes on its head. A male spicebush swallowtail was featured on the third butterfly stamp (issued January, 2013) in the U.S. Stanford University Press. All pupae from short photoperiod larvae (diapause pupae) are brown. And the big black dots on their heads and the way they’re head is a little bulbous is supposed to imitate a snake’s head. First instar larvae chew a slit or slits (near the tips of leaves) from the leaf edges toward the midribs and spin silk across the leaves. Left: recently laid egg. Biosynthesis of defensive secretions in, Sperling FAH. There are at least three generations in the Deep South (Gulf of Mexico area and peninsular Florida) with peak numbers of adults in late spring and early fall in central Florida and two generations northward (Cech and Tudor 2005, Howe 1975). During autumn and summer, these caterpillars follow each other head to tail forming long chains, which is an interesting sight to behold. Figure 3. Note the silk girdle. It is less common farther west from the Mississippi River. Like most caterpillars, the pine processionary caterpillars also look defenseless but don’t be deceived by their appearance. (Rosaceae), Zanthoxylum spp. pp. Yes, even as a baby the Pipevine Swallowtail is out to get you. Sassafras, Sassafras albidum (Nutt.) Hazel WN. The larvae of the monarch butterflies are born on the leaves of the milkweed plants. A caterpillar, in general, has two types of hair or spines on their body. 1973. Eggs are laid singly on the undersides of new leaves of the host plants (Scriber 1996). Palo Alto, California. The color (green or brown) of non-diapausing pupae is environmentally controlled (Hazel 1995, West and Hazel 1985) by detection of the color of the pupation substrate by the stemmata (simple eyes of insect larvae) (Mellencamp et al. Males are reported to drink from mud puddles (Cech and Tudor 2005, Glassberg et al. The Spicebush Swallowtail is a North American species, and related species pictured on UK Butterflies do not have similar looking caterpillars. The gypsy moth caterpillar is a serious pest of oak forests in the northern US. There is disagreement on the generic classification of the swallowtails (Hancock 1983, Miller 1987). Scriber JM, Deering MD, Francke LN, Wehling WF, Lederhouse RC. Though most of these caterpillar’s venom isn’t toxic, they are adequate to keep the predators away. 2005, Nitao 1995, Nitao et al. Bag shelter caterpillars are the larvae of the Bag-shelter Moths that are mainly found in Australia. The undersides of the hind wings have marginal pale green spots and also marginal and post-median rows of bright orange spots separated by black and blue patches (Figure 5). (1999) have identified an oviposition stimulant (3-trans-caffeoyl-muco-quinic acid) in extracts from the leaves of Sassafras albidum. 1995. The caterpillars of the cinnabar moths are heavy eaters, and they encounter a lack of food at times. This means that even a small accidental brush against them can lead to you coming in contact with a lot of spines. New York. 175-189. Pipevine swallowtail butterflies remain poisonous so many other butterflies imitate their coloring to protect themselves from predators (female Eastern Tiger Swallowtail, Red-spotted Purple, Eastern Black Swallowtail, Spicebush Swallowtail.) Which means that there isn’t a specific color code for the poisonous caterpillars. For instance, the black swallowtail caterpillars are not poisonous, whereas the spicebush caterpillars are poisonous. The hag moth caterpillars are known for their bizarre alien-like looks. Figure 19. Photograph by Donald W. Hall, Entomology and Nematology Department, University of Florida. Smithersia 2: 1-48. Owing to the severe itching and allergic reaction caused due to these caterpillars, they are commonly called “itchy grubs” in some parts of Australia. Callosamia promethea, commonly known as the promethea silkmoth, is a member of the family Saturniidae, which contains approximately 1,300 species. Early instar larva of the spicebush swallowtail, Papilio troilus L. Photograph by Donald W. Hall, Entomology and Nematology Department, University of Florida. Pupae: Pupae have two anterior "horns". can often be identified by the characteristic leaf galls (Figure 18) caused by the red bay psyllid, Trioza magnoliae (Ashmead) (Insecta: Hemiptera: Sternorrhyncha: Psyllidae) which are almost always present. I've been working with the National Wildlife Federation for the past five years. During the larval stage, they mainly feed on the leaves of the oleander and takes up the toxin on the leaves. 1958. The white markings on the abdomens of these instars resemble the uric acid deposits in bird and lizard droppings making the resemblance even more striking. Right: egg shortly before hatching. Black Swallowtail Anise - Pimpinella anisum Caraway - Carum carvi Celery - Apium graveolens Cow Parsnip - Heracleum maximum *Dill - Anethum graveolens Dutchman's Breeches - Thamnosma texanum *Fennel - Foeniculum vulgare Forked Scaleseed - Spermolepis divaricata Golden Alexander - Zizia aurea Mock Bishopweed - Ptilimnium capillaceum Northern Water Hemlock - Cicuta virosa (Extremely poisonous … Well, the risk only arises if you were to consume them, which is highly unlikely. But don’t be deceived by their looks, these caterpillars hide sharp spines between their hairs and a poison secreting gland under their skin. (1991) reported that neonate Papilio troilus starved to death rather than initiating feeding on non-lauraceous hosts (including sweetbay, Magnolia virginiana L.; tuliptree, Liriodendron tulipifera L.; and common pricklyash, Zanthoxylum americanum Mill.). Figure 2. The buck moth caterpillars are commonly seen in the southern states of the US. Carter M, Feeny P. 1999. The spicebush swallowtail is threatened throughout its range due to mortality of its caterpillar host plants from laurel wilt fungus (Raffaelea lauricola T.C. The galls on the foliage are caused by the red bay psyllid, Trioza magnoliae (Ashmead) (Insecta: Hemiptera: Sternorrhyncha: Psyllidae). Haddad NM, Hicks WM. Spicebush swallowtail, Papilio troilus L., larvae with osmeteria extruded. Figure 4. These colors are more like an indication to stay away from them! Though they lack poison like other caterpillars, they aren’t defenseless after all. Postal Service’s series of stamps for large greeting cards that require additional postage (Figure 1). One is called the urticating hair, and the other is the stinging one, and these two work differently. Postal Service’s series of stamps for large greeting cards that require additional postage (Figure 1). Caterpillars are indeed an art of nature. 64. 1975. Figure 18.

Eggs: Recently laid eggs are spherical and greenish-white or white in color (Figure 6, left). 1984. Undated. Imms A.D. 1957. It is interesting to note that these slow-moving critters that may appear to be defenseless to most have developed some interesting ways to protect themselves. Comparative mating behavior and sexual selection in North American swallowtail butterflies. For a list and contact information for native plant societies, see the American Horticultural Society’s web site. The best way to go about it is to follow the method of elimination. Scriber JM, Lederhouse RC, Hagen RH. 1979. These caterpillars have a black body and iconic white spots on them, resembling the color of a starfish. Figure 14. Courtship and mating occur in the afternoon. Spicebush Swallowtail eggs are laid singly, usually on the underside of leaves.

Tree frogs, possible mimicry models for fifth instar spicebush swallowtail, Papilio troilus L., larvae. There are about 20,000 identified species of caterpillars in the world, and only God knows how many more are there. Laurel wilt disease: Invasion potential and ecosystem impacts. Warren AD, Davis K, Stangeland M, Pelham JP, Grishin NV. The Johns Hopkins University Press. 1998. Science 150: 1733-1735. For Florida and the Deep South, the Florida Wildflowers Growers Cooperative is an excellent source of information and also has wildflower seeds for purchase. Larvae: Early instars are brown or black usually with a white spiracular stripe that often extends dorsally on the first and eighth abdominal segments (Wagner 2005) (Figure 7). (1992) reported that, based on three-choice laboratory tests, Papilio troilus females laid on average 11% of their eggs on Persea borbonia, 43% on Sassafras albidum, and 46% on Lindera benzoin. 210 pp. 2007) (Figure 13). Foodplants and evolution within, Seligman IM, Doy FA. Figure 17. A General Textbook of Entomology: Including the Anatomy, Physiology, Development and Classification of Insects. (Rutaceae), and Cercis spp. Even an accidental contact with those hollow hairs can cause burning and itching sensation along with redness and inflammation, similar to a bee sting. Miller JS. pp. 1987. Unlike the adult moths, the caterpillars are known for their pale green color with a lateral stripe of pink and creamy white down each side. These barbs sometimes break, leaving behind the small pieces on your skin, causing an allergic reaction. Owing to their cute looks, these caterpillars are not considered to be a threat by most people. (as well as Sassafrass) Here is the stage the caterpillar is in right now. Minno MC, Butler JF, Hall DW. Most of these caterpillars use their venom as a deterrent against predators and do not have enough toxicity to kill humans. The Swallowtail Butterflies of North America. Like all other venomous caterpillars, they have hollow spines on their body protruding outwards that is connected to a poison secreting gland underneath their skin. (1992) reported that soldier bugs (Hemiptera: Pentatomidae) could attack and eat swallowtail larvae without evoking extrusion of the osmeteria. These broken chitinous particles that are left in the skin causes inflammation too. Full-grown fifth instar larva of the spicebush swallowtail, Papilio troilus L. Photograph by Jerry F. Butler, Entomology and Nematology Department, University of Florida. The list of Lauraceae infected by the fungus (Smith 2015) includes all of the known hosts of the spicebush swallowtail. When an animal comes in contact with these caterpillars, they are stuck with the spines, and the venom is injected in. The subgenus name Pterourus is from the Greek roots “ptero” for wing and “ura” for tail (Borror 1960). Lederhouse RC. Figure 22. These caterpillars are known best for being hairy and processionary. 1992. However, Gatrelle (2000) maintained that only subspecies troilus occurs south through northern Florida and that ilioneus is not a valid subspecies. What makes these caterpillars extremely dangerous is the fact that they are commonly found in groups. Brower JV. Papilio troilus: The Spicebush Swallowtail. Spicebush Swallowtail Life Cycle. 345 pp. When threatened, these caterpillars regurgitate unpleasant fluids onto their attacker that keeps them safe. Because of the presence of glycosides, these caterpillars are poisonous to some birds and other predators. 2005. None of these species are poisonous, but birds avoid them because they have the same color and size as Pipevine Swallowtails.” Look for these beautiful butterflies this summer. 1983. 1998, Sperling 1993) and most similar of our swallowtails to the spicebush swallowtail. The most dangerous caterpillar is the Lonomia Obliqua caterpillar owing to its deadly venom.

Butterflies Through Binoculars: A Field, Finding, and Gardening Guide to Butterflies in Florida. The Pipevine Swallowtail’s nefarious plot begins after it hatches out of its egg. Persea species are sometimes confused with sweetbay (Magnolia virginiana Linnaeus) but can be differentiated by the presence on sweetbay of stipular scars that completely surround the stem. There isn’t a definite science behind properly identifying whether a caterpillar is poisonous or not. A quick glance, and it looks like a snake. What makes it even interesting is that these butterflies with an average lifespan of only eight weeks do not make the return trip after migration. Figure 24. The hickory horned devil looks menacing, but it’s just … Map prepared by Donald W. Hall, Entomology and Nematology Department, University of Florida. Not just to the predators, these poisonous caterpillars are a threat to human beings as well! Papilio troilus fakahatcheensis is now very rare and probably imperiled (Marc Minno personal communication). Spicebush swallowtail The spicebush swallowtail can be found in the eastern states where its range overlaps with the black swallowtail. HOSTS - a Database of the World's Lepidopteran Hostplants, Notes on swallowtail population dynamics of three. Carter M, Feeny P, Haribal M. 1999. Figure 5. The stinging rose caterpillars are the soft and cuddly caterpillars of the handsome green and pale brown moths. (Lederhouse 1990) (Figure 23), or lizards (Tyler et al. Gainesville, Florida. 2003). Swallowtail Butterflies: Their Ecology and Evolutionary Biology. Swallowtail Butterflies of the Americas. Some species that mimic Pipevine Swallowtails include Eastern Tiger Swallowtail (females), Eastern Black Swallowtail, Spicebush Swallowtail, and Red-spotted Purple. Males emerge first (=protandry) (Deering et al. CATERPILLAR OF THE WEEK: A comical face hidden among the leaves, the spicebush swallowtail caterpillar, Papilio troilus, is one of the region's most striking and well-developed predator mimics. Eggs of the spicebush swallowtail, Papilio troilus L., on camphortree, (Cinnamomum camphora [L.] J.Presl). For the venom to cause such serious injuries, it has to be injected in higher doses. Florida Butterfly Gardening. Photograph by William Barichivich, U.S. Geological Survey. The green fifth instars with their swollen thoraxes and eyespots with bulging “pupils” (Figure 8) are believed to mimic either green snakes, tree frogs (Hyla spp.) Some authors (e.g., Tyler et al. It is important to note that the venom of this caterpillar, once injected, can cause severe blood clots throughout the body, causing internal hemorrhages and eventually death. Third instar spicebush swallowtail, Papilio troilus L., larva. Spicebush Swallowtail Genus-Species: Papilio trailus Host Plants: Spicebush (Lindera benzoin), sassafras trees (Sassafras albidum); perhaps prickly ash (Zanthoxylum americanum), tulip tree (Liriodendron tulipifera), sweetbay (Magnolia virginiana), camphor (Cinnamomum camphora), and redbay (Persea borbonia). Though these bag-shaped caterpillars look harmless, they are best left alone. The prepupae wander off the host plants to pupate. Young trees are usually selected and eggs are typically laid from two to five meters above the ground. Note bulging “pupils” of false eyespots. In between those short and brown hairs covering their body, some are connected to the toxin glands under their skin. Figure 16. Occasional stray insects are observed outside the normal range. Photograph by Donald W. Hall, Entomology and Nematology Department, University of Florida. But make sure that you don’t touch them because they can cause serious allergic reactions on your skin! Historically, two subspecies have been recognized: Papilio troilus troilus, which was considered to be distributed throughout the range, and Papilio troilus ilioneus, which was considered to be restricted to the southern coastal plain including the Florida peninsula. 1991. The spicebush was most likely chosen because not only is it a native shrub with colorful and edible berries that can be used in many different recipes, but that it is also the sole food source of the Spicebush Swallowtail! Diapause pupae are brown. Only the exotic camphortree, Cinnamomum camphora has shown any resistance at all to laurel wilt (Chupp and Battaglia 2014). In general, the poisonous caterpillars all have bright and vibrant colors. Owing to the high levels of toxin in their body, most birds and the other common predators do not feed on them. Butterflies of the East Coast. Any encounter with these seemingly innocuous caterpillars can cause allergic reactions, especially on children. Hickory Horned Devil (Regal Moth) Caterpillar.

University Press of Florida. Puss caterpillars are the larval … It is interesting to note that these caterpillars form long chains when they migrate from treetops to loose soil to pupate. Nectar host plants: There are many plants that are valuable as nectar sources for butterflies. Soon after hatching, larvae eat the egg shells (Figure 12), and the residual yolk serves as their first meal (Imms 1957). Classification of the Papilionidae (Lepidoptera): A phylogenetic approach. But don’t be deceived by their cute looks, the saddlebacks can land a deadly sting that can cause burning pain and burning sensation that can last for several hours. It has a light green body with darker dots and yellow colors around its midsection. Haddad and Hicks (2000) reported that female spicebush swallowtails preferred non-pubescent to pubescent Sassafras albidum for oviposition and that the pubescent plants were suboptimal for larval development. undated) follow the system that elevates the subgenus Pterourus to generic status as proposed by Hancock (1983). Similarly, those caterpillars that are nearing the end of the larval stage can penetrate its hair into the skin of its predators and then breaking it off, leading to severe allergic reactions. 459 pp. Before pupation, full-grown larvae cease feeding and turn to a yellow color. Not all black caterpillars are safe to handle, which is why you need to be extremely careful while handling one. Although spicebush swallowtails employ extensive mimicry throughout their lifecycles, mimicking bird droppings and green snakes as caterpillars, and mimicking the poisonous pipevine swallowtail (Battus philenor) as adults, they suffer from extensive predation. The entire body of this caterpillar is covered with venomous spines that can land a deadly sting. Abdominal segments have a transverse band of six blue dots with each dot ringed by a fine black line (much thicker than those on larvae of the Palamedes swallowtail (Papilio palamedes Drury) the most closely related (Hagen and Scriber 1991, Scriber et al.
