SeasonalityAdults recorded in October, April and May (collected at light at near-freezing temperatures). IdentificationAdult antennae are dark brown with white scapes. Vertex of the head is totally black. Spur formula is 1, 1, 1 and brown. Forewings are hyaline in the membrane with scattered patches of light grey-brown. In males, the cercus is large, bifid and the ventral lobe is longer and narrower. Clasper is tapered and broadly triangular. The distal process is slender, and finger-like. This species is best recognised by very late or very early seasonality, cold grey irrorate forewings and delicate appearance (Nimmo, 1971).
