Hayhurst's Scallopwing

Staphylus hayhurstii

Two small white dots at bend of FW and a small cell-end dot are more prominent in females. Scalloped wing edges usually most noticeable on HW. Below: Almost never seen with wings closed.

Habitat: Mainly disturbed habitats where its food plant grows. Often prefers dappled shade.

Flight Period: Two or three broods, peaking in May, July, and September. Extreme dates: 5/14—9/23.

Larval Food Plants: Mainly Lamb’s Quarters (Chenopodium album).

Overwintering Stage: Larva.

Best Locations: Higbee Beach WMA, and Cape May Point SP.

Comments: This small, dark butterfly flies weakly and very close to the ground in vegetation, so that it is easy to overlook. Occupies the same habitat as the similar Common Sootywing, which has white spots on top of head, and lacks the Scallopwing's gold and silver flecking.
