Identification

This is a large brush-footed butterfly with a 3 to 3½ wingspan. The male and female are identical in appearance but the female is slightly larger than the male.

The upperside of both wings is dark bluish-black with a broad, white, postmedial band. The forewing is rounded at the tip. It has a few white spots near the apex and a row of light blue, crescent-shaped, marginal spots. The hindwing has a row of reddish-orange submarginal spots and two rows of light blue, crescent-shaped, marginal spots.

The underside of both wings is dark brown with the white band, submarginal spots, and subapical spots carried through from the upperside. Both wings also have orangish-red and blue spots near the leading edge and two rows of light blue, crescent-shaped, marginal spots.

The caterpillar is up to 2 long. It is a bird dropping mimic. The thorax and abdomen are mottled medium and dark olive green. A pair of long, black, spiny, branched projections (scoli) extend over the head from a hump on the second thoracic segment. There is a pair of large, greenish-yellow humps on the on the upper (dorsal) side of the second abdominal segment. Each hump is tipped with a small cluster of short white spines. There are similar, smaller humps on the seventh and eighth abdominal segments. A white subspiracular stripe extends from the second to the last abdominal segment. A white “saddle” on the dorsal surface from the fourth through sixth abdominal segments extends down the sides near the middle and merges with the subspiracular stripe. The head is brown and has a pair of short, brown scoli. The prolegs are brown.

Mature caterpillars are found from late May onward.

Larval Food

Usually leaves of birch, willow, quaking aspen, and chokecherry, but also American basswood, plains cottonwood, hawthorn, oak, serviceberry, and other trees.

 
Adult Food

Sap flows, rotting fruit, aphid honeydew, carrion, dung; rarely flower nectar.

 
Life Cycle

In the fall the third stage caterpillar of the second brood forms a shelter (hibernaculum) by rolling a leaf and tying it with silk. It overwinters in the hibernaculum.

The range of this subspecies overlaps that of the red-spotted purple in the lower third of the state. Where the ranges overlap the subspecies interbreed and produce offspring with intergrading characteristics.

 
Behavior

Adult butterflies are often seen sunning themselves on gravel roads.
