The Banded Woollybear Caterpillar Moth gets its descriptive name from the appearance of the caterpillar, not the adult moth. The moth has a mustard-yellow coloring on its forewings with a few black dots on each. The hindwings are pink with gray dots on them and are only visible when the wings are spread open and flat. They can be found in pastures, meadows, fields and at the sides of roads.
Its famous caterpillar is black at both ends with a red band in at the waist. It is covered entirely in bristles. It used to be believed that the amount of black coloration forecasted how bitter the winter would be, but it is actually related to the caterpillar's maturity, not the weather. The hairy little caterpillar feeds on many kinds of low-growing plants, but is not a pest on the farm or in the garden. It is not uncommon to see them on sidewalks, curbs, roads and other people areas in the autumn.
