scientific name    Acronicta cyanescens    

Dry montane forest

Collected in Alberta in late June and early July.

A medium-size (4.5-4.7 cm wingspan) powdery light grey moth with few markings. Forewing markings consist of a short, very fine black basal dash, a slightly larger black anal streak, a few dark scales marking the reniform and in some specimens traces of the postmedian line. The grey fringe is checked with black between the veins. The hind wings are dirty white, with darker grey-brown scales lining the veins and forming a thin terminal line. Antennae simple. Overall a very neat, clean looking moth compared to most Acronicta species. The closely related A. lepusculina is darker grey and has more prominent markings. Acronicta dactylina is also better marked, and lacks any trace of a basal streak.
