Identification
Adults
Bulia deducta is a very rare migrant in the Pacific Northwest. It is a medium-sized species (FW length 16 mm). The forewing is medium gray with a variable complex pattern of light gray, black, and red-brown. The most prominent marks are a pale transverse area between the antemedial and medial lines, and a similar pale area between the reniform spot and the postmedial line which is ballooned laterally like the margin of a giant reniform spot. The distinctive hindwing is pale yellowish white, with a dark gray marginal band that envelops an orange and black eyespot and white fringe.
This species can be identified from similar Drasteria species by the unique orange and black mark at the hindwing margin.
