Some of the poisonous caterpillars are the Puss caterpillar, Buck moth, Gypsy moth, io moth, Saddleback, and Flannel Moth. Caterpillar venoms, in general, have not been well-studied. Pelaia A. Photographs by Donald W. Hall, University of Florida. Stings commonly result in a nearly immediate painful nettling and pruritic (itching) reaction followed by formation of a localized wheal (welt) and erythematous (reddened) flare around the wheal. (1960) recommended studies with Io moth caterpillar venom as a model to determine the chemicals responsible for the pruritic symptoms of caterpillar stings. I hope so, because if these caterpillars come into contact with your skin, however lightly, you’ll have a terrible, ichy rash to show for it. Fullard JH, Napoleone N. 2001. Princeton, New Jersey. Io Moth Caterpillar. 1994 (1996). The spines that cover the caterpillar are connected to poison glands. Stinging spines protect slug caterpillars (Limacodidae) from multiple generalist predators.

Systemic symptoms are rare. New York, New York. Although Io moth larvae are polyphagous, they may have regional host preferences (Tuskes et al. Darker male forewings are more common in southern populations and the darker coloration is often characteristic of males from diapausing pupae (Manley 1990[1991] & 1993, Sourakov 2014). Figure 20. 2008, Hughes & Rosen 1980, Rosen 1990). Families Ceratocampidae, (exclusive of Ceratocampinae), Saturniidae, Hemileucidae, and Brahmeidae.

For photographs showing more of the color variation of adult Io moths, see Ferguson (1972) and Sourakov (2014). Reared adults mate readily in small cages, or females may be tethered outside to attract wild males. When ready to molt, early instar larvae queue into rosettes with the heads facing outwards (Russi et al. Recommendations for your apiary in December 2020: This calendar is meant to be a reference point for management and is not comprehensive. The actual cocoon is “inside there,” surrounded by a mesh-like membrane that’s sticky, and knits together a coating of leaves or other debris that surrounded the area where the caterpillar pupated. Chitin particles of about 10-40 µm in size are known to invoke pro-inflammatory immune responses, but smaller chitin particles may actually be anti-inflammatory (Alvarez 2014, Da Silva et al. Figure 21. Photograph by Donald W. Hall, University of Florida. Venomous Spines: Virtually the entire bodies of larvae are protected by venomous spines. Figure 16. New York.

Diapause pupae may require a chilling period prior to emergence. Without magnification, female antennae appear almost thread-like. Photograph by Donald W. Hall, University of Florida. While gregarious, they form a long train to move from leaf to leaf or to a different branch. You are correct that the caterpillars are capable of stinging. Io moth, Automeris io (Fabricius), eggs. Oak Leaves: The (Nearly) Universal Caterpillar Food . Part 1. This one is easy to identify in many ways. Cleaning cages A bilateral gynandromorph of. History. Manley (1993) conducted detailed studies of diapause and reported that northern populations are univoltine (one generation per year), those from coastal South Carolina, the Gulf States, and north Florida are probably bivoltine, those from Orlando, Florida south to a line intersecting Bradenton-Sebring-Fort Pierce probably have four generations, and more southerly Florida populations probably have four or five non-diapausing generations. For a more complete list of synonyms for Automeris io, see Ferguson (1972) or Heppner (2003). Hampton, England. They’re white, each with a blue spot on top and a yellow spot on the side. These whorls of spines arise from small tubercles. The Io lives only to mate and lay eggs. The moth able to consume that can dissolved in water.

Here are different instars together: Here, again, are four presenting a couple of instars. Larvae: Tuskes et al. Photograph by Donald W. Hall, University of Florida. And be sure you raise the caterpillars in some kind of contained, protected area where they won’t accidentally come into contact with you or anyone else. With the exception of Cape Cod and some of the Massachusetts islands, it is now rare in New England where it was once common, and its populations have declined in the Gulf States (with the exception of Louisiana) since the 1970s (Manley 1993). Io Moth Caterpillar stung my dad behind ear? 1979. Control would only be required if they present a stinging hazard in landscape plants. Full-grown (usually fifth instar) larvae are approximately 60 mm (about 2⅜ in.) Wild-caught females have often already mated. Again depending on the species of moth, the pupal stage can last up to four years. Moths of the Limberlost. The antennae of males are quadripectinate.
