IdentificationA small (1.7-2.1 cm wingspan) broad winged dark yellow-brown and grey moth. Specimens of most Eupithecia species, including maestosa, are best identified by examining the genitalia (illustrated below). The absence of a white spot in the tornal area of the forewing will separate it from the very similar Eupithecia columbiata.

Life History Poorly known. Adults are nocturnal and come to light. The larvae have been described by McGuffin (1958). The larval host or hosts are unknown. Range A western species, found from extreme western AB west to Vancouver Island, north to northern BC and south to Texas. In Alberta known only from Waterton Lakes National Park (Bolte, 1990). Notes The illustrated adult on the Moths of Canada website with white tornal spots appears to be a misidentified specimen of E. columbiata. Specimens of both sexes are illustrated in color, life size, in Bolte (op cit.).
