Banded woolly bear

Pyrrharctia isabella

Description:

Fuzzy and spiky orange and red caterpillar. This caterpillar was crawling fast on the pavement.

Habitat:

Urban.

Notes:

From Wikipedia: The woolly bear caterpillars don't inject venom and are not hazardous However, they will play dead if picked up or disturbed. Handling them is discouraged, however, as the bristles may cause irritation in people with sensitive skin. This species is a feeder, it feeds on many different species of plants, especially herbs and leaves. The banded woolly bear larva emerges from the egg in the fall and over winter it is in its caterpillar form. It survives winter freezes by producing a cryoprotectant in its tissues. It is the larvae of this species which are the subject of common folklore, which has it that the forthcoming severity of a winter can be predicted by the amount of black on the caterpillar; this is the most familiar woolly bear in North America. But in fact, larvae produced in the same clutch of eggs can vary from mostly red to mostly black, even when reared under the same conditions, and this variability invalidates any actual temperature-related trends that may otherwise be evident.

They can really book when they want to. I was trying to photograph a beetle the other day and it kept running away from the light.

It was moving so fast, it scared my daughter. I'd never seen a caterpillar crawl that fast. It was heading for the parking lot. I don't know if it made it, but I did see another woolly bear on a bush in the park today.

Thank you. I've never heard of or seen this caterpillar before.

I read up on the Wooly Bear from your wiki link, I guess we're going to have a warm winter :)
