Identification

See this annotated example on iNaturalist. Based on the subspecies kerrvillaria in Texas:

a. FW crossed by two nearly complete fine dark lines, the inner one nearly/actually touching the dark cell spot; both lines are continued across the HW.

b. Dark smudges in a couple of patches along the inner side of the thin white subterminal line; note also that the white subterminal line does not form a conspicuous white dot in the outer angle;

c. Each abdominal segment has a combination of a dull white (buff) spot and a small blackish inverted chevron, resulting in an interrupted line of dark dots down the center of the abdomen; and

d. At the rear of the thorax, there is a conspicuous pale/white triangular patch which is typically bisected by black (with a dark area immediately in front of it). In the Common Pug Moth, this pale spot is either absent or not bisected by black.

Range

Arizona, Utah, and Colorado.

ssp. kerrvillaria is found in Texas (2)
