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.
