Species guidance


Identification: A large skipper with a pale medial band on the hindwings below. Above the male veins are often lined with black and the female has little orange dorsally.

Habitat: Bluff prairie in Wisconsin. Found in both sand prairie and silt loam prairie in Illinois (Panzer).

Nectar Source: Nectaring on black-eyed susan in Grant Co.

Host Plant: Andropogon gerardi in Illinois. Uses eastern grama grass (Tripsacum dactyloides) in Missouri.

State Distribution: Collected once in Grant County.

Global Distribution: Found in IL and IA along major rivers, MO, KS, and IN. Another range extends along the coastal plain from TX to FL up to VA where the species inhabits coastal wetlands.

Status Comments: Very restricted distribution.

Phenology: Late June and July.

Life and Natural History: Branded skipper (Hesperiinae) larvae build shelters that are made of tied leaves or in the base of the hostplant from which they go out at night to feed. The byssus skippers overwinter as fourth stage larvae. Pupation occurs within a dense cocoon at the base of the hostplant.

Inventory, Monitoring and Research Needs: Foodplant is unknown for certain.
