Distribution and habitat[edit]
It is found in the United States in isolated colonies in peninsular Florida, the Gulf Coast, south-east North Dakota south to southern Texas and the Colorado Front Range. Strays are found up to New Jersey to northern Arkansas. It is considered possibly extirpated from New York, Minnesota, Wyoming, Illinois, North and South Carolina, Alabama, Iowa, Georgia, and Montana, and definitely so from Pennsylvania.
Description[edit]
The wingspan is 29–37 mm. There is one generation with adults on wing from June to July in the north and west. In the south there are two generations with adults on wing from April to September.
Taxonomy[edit]
There are two subspecies:
- Atrytone arogos arogos (nominate subspecies)
- Atrytone arogos iowa
Diet[edit]
The larvae feed on Andropogon gerardi, Panicum, Calamovilfa brevipilis and other grasses. Adults feed on the nectar from flowers of purple vetch, Canada thistle, dogbane, stiff coreopsis, purple coneflower, green milkweed and ox-eye daisy.
