General DescriptionA medium-size (2.8-3.6 cm wingspan) broad-winged dark black-brown diurnal moth. The forewings are dark brown, with a blackish antemedian band prominently toothed on its proximal side, and a narrower post-median band with a dark triangle at its upper end. The terminal area is broadly light brown. The hindwings are black-brown, with one or two narrow faint postmedian lines and a broad orange-brown terminal band. The antennae are simple and the sexes are similar. Other Alberta grass-moths (Caenurgina sp.) are lighter grey or grey brown in color. In flight Euclidia greatly resemble skippers of the genus Erynnis; they flush from the ground and fly rapidly for 20 meters or so before dropping back to the ground.
