Variable Girdle Moth
Enypia venata (Grote, 1883)

Family: Geometridae
Subfamily: Ennominae
Identification: A mid-sized, grey geometrid with heavy grey speckling and a dark broad median band, with a heavily scalloped border. Hindwing paler, with a faint PM line. Discal spot black, not white as in Caripeta species. Very similar to Nepytia species (particulary freemani), but in Enypia the forewing PM line comes closest to the wing margin near the apex (where it joins the costa), and in Nepytia the PM line is is nearest the wing margin in the subapica (not apical) area. Distinguished from E. griseata by the AM line, which jogs out to the discal spot in venata - the discal spot is well-separated from the AM band in griseata.
