Are the stiff hairs, or bristles, covering the Woolly Bear caterpillar venomous or stinging?

Answer

No, the bristles are harmless to the touch.

A key characteristic of the Woolly Bear caterpillar is that its dense covering of stiff hairs, while giving it a fuzzy appearance, does not pose a threat of stinging or venom injection. Unlike certain other hairy caterpillars whose bristles are urticating and can cause skin irritation, the bristles on the *Pyrrharctia isabella* larva are explicitly described as being harmless when touched. This lack of stinging capability makes them relatively safe for close observation or gentle handling if necessary.
