Caterpillars (long, fuzzy, segmented insects) are unable to pierce the skin with their bite. However, their hairs may get into the skin or eyes, causing symptoms in the area where the hairs entered.
Problems also can occur if someone breathes in caterpillar hairs that have been released into the air, or eats caterpillars.
