IdentificationA very small (1.4-1.9 cm wingspan) broad winged grey and reddish brown moth. The forewings are dark brownish grey except for the reddish brown costa and poorly defined wide postmedian band. Hind wings slightly paler brownish grey. Second segment of abdomen with darker transverse band. Sexes similar. The small size and reddish brown postmedian area will separate coloradensis from all other Alberta Eupithecia. Leptostales ferruminaria is similar in size but is much brighter rufous-red and has more angular forewings.
