Appalachian Brown (Satyrodes appalachia [R. L. Chermock])

Wing span: 1 7/8 - 2 1/4 inches (4.8 - 5.7 cm).

Identification: Wings are medium brown. Lower side of forewing with the two end eyespots larger than the middle two; spots may not touch. Dark line inside the hindwing row spot is sinuous, not zigzagged.

Life history: To court females, males patrol and occasionally perch in small sunlit openings. Females lay eggs singly on or near the host plants; caterpillars feed on leaves at night and hide at the base of the plant during the day. Third- and fourth-stage caterpillars hibernate.

Flight: One brood from July-September in the north, two broods from June-October in the south.

Caterpillar hosts: Sedge (Carex lacustris) and giant sedge (Rhynchospora inundata) in the sedge family (Cyperaceae).

Adult food: Sap and other non-floral resources.

Habitat: Wooded wet swamps, shrub swamp, forest edges, and along slow-moving streams.

Range: Eastern Minnesota east to central New England and southern Quebec south through the Appalachians and coastal plain to Mississippi and Alabama. Isolated population in north peninsular Florida.

Conservation: Not usually required.

The Nature Conservancy Global Rank: G5 - Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.

Management needs: None reported.
