Butterflies, like bees, are pollinators of crops and wild flora, and the Baltimore Checkerspot is no exception. Its body or thorax is dark brown, a color which extends to its wings, spotted white and then orange on their edges. As part of the family Nymphalidae (Brush-footed Butterflies), it bears hairy forelegs too short for walking. The prominent knobs on its antennae also are a trait of this butterfly family.

Over a period of a few weeks, each caterpillar, as it grows, will molt or shed its skin several times before reaching its full size. Following the last molt, the pupa or chrysalis appears. Within a flexible shell, the chrysalis is a semiliquid in which the butterfly forms. From it emerges an adult butterfly.
The Baltimore Checkerspot Butterfly now is rare in Maryland. While it inhabits wetlands in the western and central regions of the State, its numbers have diminished. Formerly found in fifteen counties, now it only appears in seven. Most are in western Maryland, particularly Garrett County.
