Some of the black-spotted white arctiids are
called "ermine moths" - not to be confused with the very different
yponomeutid "small ermine moths". The present species is also called
the Virginia Tiger Moth, though it is by no means restricted to Virginia and
is quite common in our area. The caterpillar is the Yellow Woolly Bear, and
its colour can vary from yellow to light brown. It feeds on low-growing plants
such as docks, thistles, plantains and dandelions. Winter is spent as a pupa
in a cocoon.
