Brush-footed Butterflies (Nymphalidae)
Identification Butterflies and Moths of North America, a website hosted by Montana State University. The upperside is white with light brown markings and a double row of light crescents at the margins. Forewing has one round, black spot; hindwing has two. The winter form is larger and paler; the summer form is smaller and darker. The males patrol and occasionally perch to find females. Eggs are laid singly near the host plant or under its leaves. The wingspan is usually about 3 inches. The caterpillar host plants are water hyssop, petunias, and milkweed. Adults visit Shepherd's Needle, Cordia, Casearia and composites. Its preferred habitat is open, moist areas at edges of ponds and streams, along shallow ditches, weedy fields, and parks.
