What is the technical name for the stiff hairs that cover the Woolly Bear caterpillar?

Answer

Setae

The bristly exterior appearance of the Woolly Bear is due to its covering of stiff hairs, which are technically referred to as setae. It is important to note that despite their prickly appearance, these setae do not possess stingers, meaning the caterpillar is harmless to touch. However, general wildlife etiquette suggests leaving any undisturbed wildlife alone, regardless of whether it possesses venomous attributes.
