    Banded Woollybear Caterpillar Moth - (Pyrrharctia isabella)

    The incredibly bristly Banded Woollybear Caterpillar is somewhat slow-moving, giving observers plenty of time to look, but be sure not touch.

    Staff Writer (10/20/2014): 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.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
