|scientific name Eupithecia coloradensis |
The sole Alberta specimen is from the floodplain of the lower Red Deer River in the Grasslands region, north of Bindloss. The specimen was collected in a shrubby area on the riverbank.
A 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.
Very poorly known. The Alberta specimen was collected at light. The larval stages and host plants are apparently unknown. The Alberta specimen was collected on July 27, 2004.
Western PQ and western ON south to NC, west to NM, AZ, CO and se Alberta.
This is a rather insignificant looking little moth, about which very little is known. The single Alberta record extends its range considerably from Colorado and western Ontario!
