Did You Know…
Very similar to the Green Skipper (Hesperia viridis) and can only reliably be told apart by examination of genitalia and color of felt-like material in the stigma. The felt is colored yellow in this species and black in the Green Skipper. Females deposit eggs singly on or near the host plants; caterpillars feed on leaves and take shelter in tied-together leaves. Caterpillars form partially underground in shelters of silk and ground litter (Pyle, 1981). Caterpillars overwinter. This species hilltops.
