Holorusia hespera, the giant western crane fly, is a species of crane fly in the family Tipulidae. It is found in western North America.[1][2][3]

H. hespera is the largest North American species of cranefly, with wings reaching lengths of 40 mm (1.6 in). The species is noted to lack wing interference patterning on the glossy amber colored wing surface, suggested to be a result of the wing thickness. The wing surfaces are textured with ridging and folds and the coloration is uniform across the wing.[4]
