Virbia opella (Grote, 1863)
FWL: 11mm (1)
WS: 22-28 mm, based on Moth Photographers Group specimens (2)
Adult: A highly phenotypically variable species ranging from a dark charcoal form to a pinkish form. Nearly all have a brown discal spot in the hindwing, although the spot is obscured in the dark form, and paler forms may lack the discal spot. Head olive brown. Antennal scales olive brown. Third segment of labial palpus exceeding front of head by at least half of entire length, first and second segments orange rufous, third segment olive brown. Legs cinnamon, occasionally suffused with orange-rufous scales. Dorsal surface olive brown to dark drab with a sepia discal spot present, ventral surface clay suffused with salmon extending from adbasal region through medial region. (1)

Occurs from Maine, west to Illinois and south to Texas. (1)
