Wing span: 2 1/8 - 3 inches (5.4 - 7.6 cm).

Identification: Upperside forewings of both sexes have yellow "dog's head" surrounded by black. "Eye" does not touch black border. Female similar, with duller, more diffuse black areas and 2 seasonal forms: underside hindwing of wet season "summer" form is yellow; that of dry season "winter" form is mottled with black and pink.

Life history: Males patrol open areas for females. Eggs are laid on the undersides of terminal leaves of host plants. Adults overwinter in reproductive arrest.

Flight: Three flights in the southern states from May-June, July-August, and September-April. Northern colonists have one generation per year, or do not reproduce at all.

Caterpillar hosts: Small-leaved plants in the pea family (Fabaceae) including alfalfa (Medicago sativa); prairie clovers (Pentalostemon), indigo (Dalea), and clover (Trifolium) species.

Adult food: Nectar from flowers including alfalfa, coreopsis, houstonia, and verbena.

Habitat: Dry, open areas such as short-grass prairie hills, scrub oak groves, open woodland, washes, road edges.

Range: Resident in South America north to southern Texas and peninsular Florida. Stray or temporary resident from central California northeast through the Great Lakes area and all the eastern states.

The dogface is a somewhat unusual find for south-west Ohio but we did have one in our garden in August. A nice addition to our lepidoptera list for 2010.
