Saddleback Caterpillar (Acharia stimulea)
From Wikipedia: The saddleback caterpillar (Acharia stimulea, formerly Sibine stimulea) is the larva of a species of moth native to eastern North America. It is also found in Mexico. The species belongs to the family of slug caterpillars, Limacodidae.
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. It has a pair of fleshy horns at both ends. These and most of the rest of the body bear urticating hairs that secrete an irritating venom. Contact with the hairs causes a painful, swollen rash and sometimes nausea in humans. 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. The hairs should be removed from the skin immediately to prevent more venom spread. The cocoon may also have irritating hairs, and hairs from the larva can fall on surrounding objects.
The larvae feed on a large variety of plants.
Several of these caterpillars were feeding on the leaves of some of our backyard pond plants.
