Silvery Checkerspot, Chlosyne nycteis

Silvery Checkerspot

Chlosyne nycteis

Description:
Above, it is very similar to the Gorgone Checkerspot, with orange wings and black markings. The row of submarginal spots on the hindwing usually has one or two of the black dots with white in them. Below, there is large white crescent in the middle of the hindwing margin and a distinct row of white median ellipses that are obvious in fresh specimens.

Habitat:
Found in a variety of habitats including woodland edges, roadsides, and, marshes.

Overwintering Strategy:   Mid-stage Caterpillars

Flight:   
One brood throughout most of the state, although it may occasionally have a partial second generation in the southern part of the state.

Caterpillar Host Plants:
Many different composites including black-eyed susan (Rudbeckia), sunflowers (Helianthus), and wingstem (Actinomeris alternifolia).

Notes:   
The Silvery Checkerspot can be found in a variety of habitats. This species is fairly easy to identify when it is fresh and you can see the underside, but it wears more than other butterflies, tends to look very plain, and loses it contrast, as it gets older.

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.
