Bruceia pulverina Neumoegen, 1893




Bruceia pulverina is a small (FW length 11 mm), rounded-winged, smudgy yellowish and brown tiger moth. The forewing is light yellow tan with powdery dark gray brown markins over the basal area (to the postmedial line) and at the base of the fringe. The discal spot is a pale zigzag line and the orbicular spot is evident as the light yellowish filling without a dark outline. The hindwing is translucent pale yellow gray, strongest yellow at the outer margin including the fringe, with a pale gray marginal band. The head and thorax are medium tan, with a slightly lighter abdomen.

No other Pacific Northwest macromoth species are likely to be confused with this species. It is more likely to be mistaken for a micromoth (many families of small moths not included in the scope of this project) due to its small size and dingy color.
