Description: The Stripe-winged Baskettail is a medium-sized brown dragonfly with yellow markings along the side of the abdomen. The abdomen is relatively narrow, and somewhat constricted at the base. The thorax is brown and rather hairy. The wings are clear except for small black spots at the base of the hindwing. It ranges in size from 38-48 mm (1.5 - 1.9 inches).
Similar species: The Stripe-winged Baskettail is very similar to several other species of Baskettail (Epitheca sp.) in Virginia, but can be distinguished by the relatively narrow and constricted abdomen. Terminal appendages are longer than those of related species. See illustrations in Paulson (2011) p. 398.
North American Range: The Stripe-winged Baskettail ranges in the Eastern U.S. from Iowa and New Jersey south to the gulf states and east Texas. Absent from higher elevations of the Appalachians. There are records from several eastern counties in Virginia.

Flight season and broods: The flight season for the Stripe-winged Baskettail in Virginia ranges from 21 May - 2 June.
Aquatic Habitat: The Stripe-winged Baskettail prefers ponds, lakes, and slow streams. "More likely to be on streams than other small baskettails" (Paulson, 2011).
Behavior and Ecology: Most baskettails fly early in the season and are gone by early summer.
Population trend and potential threats: Mostly unknown. Though regarded as Possibly Extirpated in Pennsylvania, and Imperiled to Critically Imperiled in four other states (NatureServe, 2011), the difficulty of identifying this species in the field combined with few knowledgeable observers may obscure its true status.
Management practices: Monitor and protect occupied habitat.
