Wing span: 6.0 to 7.5 cm.

Flight time: First migrants begin appearing by early-mid June in most years, establishing two broods later in the season, one flying late July-mid August, and the second from September-October.

Status: Spring and early summer southern stray; summer resident.

Distinguishing features: The dogface is named for the yellow dog's face (including an eye) framed in the black border of the upper, forewing surface. Wings are yellow below. Late autumn specimens may show a rosy cast to the underside, and have been referred to as the form rosa.

Distribution and habitat: Frequently found in the Loess Hills, it is incidental throughout the rest of the state. Individuals demonstrate a strong preference for dry meadows and prairies.

Natural History: Larvae feed on a large number of legumes, including the native leadplant, prairie clover, and false indigo. Adults, larvae, and eggs are unable to withstand harsh Iowa winters, and this species must repopulate the state each year via migration from the south. Because of this, population sizes may fluctuate greatly on a yearly basis.
