Woolly bear (Isabella tiger moth)

How to recognise it

The famous 'woolly bear' caterpillar is fuzzy with a rusty-orange band between black ends; the adult Isabella tiger moth is a plain yellowish-orange moth.

Is it dangerous?

Harmless to handle — its bristles don't sting, and the folklore that its band width predicts the winter is just folklore.
