Embed Saddleback Caterpillar - Acharia stimulea

Saddleback Caterpillar - Acharia stimulea I was SO excited to find this caterpillar in my mother's garden this weekend! 

The caterpillars have a truncated, slug-like body that is not typical of other lepidopterans. The prolegs are concealed under the ventral surface of the body. They have aposematic coloring with dark brown anterior and posterior ends with a contrasting bright green pattern blanketing the dorsal midsection.

It is a medically significant insect due to the presence of venomous, urticating spines and hairs! These hairs/spines secrete an irritating venom that causes a painful, swollen rash and nausea in humans.

Habitat: Spotted in a rural, backyard garden.
