Brown Elfin, Callaphrys augustinus

Brown Elfin

Callaphrys augustinus

Similar in size and shape to the other state Hairstreaks and Elfins. Below it is a darker brown towards the body and lighter reddish brown marginally. No tails.

Bogs and wooded areas in the northern part of the state where heaths are prevalent.

Overwintering Strategy:   Chrysalis

One brood. Has been observed from late April until early June.

The Brown Elfin is widespread throughout the northern half of Wisconsin, but is seldom very abundant. The Elfins, like the Hairstreaks, have a very short flight period in an area, and coupled with the spring flight time, it is difficult to get out into the field when they are actually flying. Consequently, even in an area when you know they occur, you may not be able to observe adults flying every year.

Overwintering Strategy

Two-way migration: Adult migrates from Wisconsin to Central Mexico
Small migration: Adult migrates from Wisconsin to southern US
Immigrant: Adult migrates into Wisconsin from warmer areas and don't fly south in winter
Adult Butterfly: Hibernates overwinter as an adult butterfly
Eggs: Eggs laid on stems, twigs or foot plants overwinter in diapause
Caterpillar: Caterpillars make nests on the base of plants and hibernate until spring
Chrysalis: Caterpillars shed their last skin, form a chrysalis and enter diapause.
