Habitat: Herbaceous wetlands dominated by grasses and sedges.

Flight Period: One brood, late May to mid-June. Extreme dates: 5/20—6/21.

Larval Food Plants: Wetland grasses, possibly Calamagrostis.

Overwintering Stage: Larva.

Best Locations: High Point SP was the only location known in NJ.

Comments: Arctic Skipper was first reported in NJ in 1986, and for the next 20 years or so it was not unusual to see 10-15 individuals/day nectaring on Wild Geranium (Geranium maculatum) along Sawmill Road along with Hobomok and Pepper and Salt skippers. Our warming climate may be responsible for NJ's loss of this tiny jewel of a butterfly.
