In some cases, more severe reactions to the venom can occur, including a systemic condition called erucism or acute urticaria, for which severe symptoms may include migraines, gastrointestinal symptoms, asthma complications, anaphylactic shock, rupturing of erythrocytes, and hemorrhaging. Contact with the hairs causes a painful, swollen rash and sometimes nausea in humans. These and most of the rest of the body bear urticating hairs that secrete an irritating venom. It has a pair of fleshy horns at both ends. The larva (caterpillar) is primarily green with brown at both ends and a prominent white-ringed brown dot in the center which resembles a saddle.
The species belongs to the family of slug caterpillars, Limacodidae.

Whether you love identifying caterpillars in the wild or determining friend from foe in your garden, here's a before-and-after look at some of Mother Nature's most notable species. "Instar" refers to the developmental stage of an arthropod between its various moults.Īfterward, butterfly caterpillars molt one final time into a hard chrysalis to begin their magical makeover, and moth caterpillars (with a few exceptions) wrap themselves in a silky cocoon. They grow so much during their brief lives that they typically shed their skin several times, often revamping their appearance from one instar phase to the next. What caterpillars all have in common is the incredible metamorphosis they undergo on their journey from egg to butterfly or moth.Ĭaterpillars represent just one stage of this transformational trek-the larval stage-during which their main purpose is to eat and grow. But the caterpillars they start from-with a variety of colors, shapes, markings, and armor-can be equally captivating. It's hard not to be captivated by the fluttery, fragile beauty of butterflies and moths.
