Apogeshna stenialis (Guenée, 1854)
the species was originally placed in the genusIsopteryx
Explanation of Names
See genus guide page for possible origin of that name. Specific epithet "stenialis" may refer to an ancient Greek nocturnal fertility festival, Stenia. This festival involved bread made in the shape of "snakes and phalluses". Perhaps this is the allusion--based on the sinuous wing markings! (Based on Internet searches.)
Wingspan about 17 mm, based on photo by Jim Vargo at MPG
