The wingspan is 29–38 mm. Like other hairstreaks, each hindwing has two tails near the tip. The shorter, upper tail is very short and often does not look at all like a tail. The upperside is brown grey, while the underside of the hindwings is grey. Adults are on wing from June to August in one generation per year. They feed on flower nectar of various flowers such as butterflyweed, milkweeds, and thistles.[3]

The larvae feed on the leaves of Salix species, including S. nigra and S. sericea. The species overwinters as an egg.
