Identification
Adult - two forms, one with plain blackish wings, the other with distinctive yellow spots - 1 pair near wing base and another pair at tip. Both have diagnostic yellow abdomens.
Female abdomen segment 1 black, rest yellow-orange, sometimes dusted with tiny dark flecks. Abdomen color is brighter in females. Male abdomen has wide black median area, widest on segment 1, narrowing to tip, sometimes black area is separated with yellow-orange, so black appears as spots or center stripes. Male abdomen has yellow to orange tufted, flared projections on each side of abdomen tip that protrude beyond wing edges. Abdomen color and flaring is unique.

Disturbed lands, railway rights, industrial lands.
Season
