New Jersey Butterflies

Two-spotted Skipper

Euphyes bimacula

Identification: Very small—FW ≥0.6". Sexes similar below. Above: Male FW brown with small, dull-orange patch in center crossed by dark, jagged stigma. Female FW dark brown with pale 2-spot "bracelet" and usually crossed by 3 additional pale spots. HW in both sexes variably tawny, usually unmarked. Below: FW and HW yellow-orange to dull brown with pale veining. Best distinguishing characteristic is bold white line along bottom edge of HW. Similar skippers: Arogos Skipper looks similar below but is fairly bright orange, lacks the white line on the HW, and does not occur in acid-bog habitats. Swarthy Skipper is smaller, all-dark above, and occurs in dry, upland habitats.

NJ Status and Distribution: Resident. Classified as Special Concern in NJ. Very rare. Currently known from only one location each in Burlington and Ocean counties. Formerly more widespread throughout.

NJ Range Map-Two-spotted Skipper

Habitat: Acid bogs. Not known to visit gardens probably because of rarity.

Flight Period: One brood—mid-June to mid-July. Extreme dates: 6/9—6/30.

Larval Food Plants: Wetland sedges in the genus Carex, but possibly other sedge genera.

Overwintering Stage: Mid-stage larva.

Best Locations: Lakehurst Bog, Franklin Parker Preserve.

Comments: Sometimes found nectaring on Goldencrest (Lophiola aurea). May occur in other acid bogs on the coastal plain but butterfliers are not a very venturesome lot and so keep going back to the usual spots. Since this species has a generally northern distribution it could occur in North Jersey bogs as well (where it was formerly reported).
