|Description:||This 2001 photograph depicted a right lateral view of a poisonous saddleback caterpillar, which is actually the instar, or developmental stage through which the saddleback caterpillar moth, Sibine stimulea, passes on its way to becoming an adult, or imago moth. Note that the head region had lifted off of the branch upon which the caterpillar was crawling. Beware, for the spines, also known as urticating hairs, emanating from its dorsal protuberances are capable of delivering a very painful sting, due to the irritating venom they secrete!!|
These moths are native to the eastern region of North America, and its instar is also known as the packsaddle caterpillar. A solitary specie, this caterpillar is often found on deciduous trees within its habitats. Note the bright breen midsection with its mid-dorsal round brown, white-ringed “saddle-shaped” spot.
