Often confused with Phigalia strigataria
; Can be separated by the following:
In denticulata, a very distinct dark “tooth” is located on the M1 vein where it comes off of the discal cell. This is seen as the “3rd tooth” from the costa, evenly spaced along the PM line of denticulata. In strigataria, this marking is either absent (giving the appearance of a gap between two pairs of “teeth”) or greatly reduced to only being a diffuse black spot. See following image for visual.
) has a less-mottled forewing, and a less-toothed and straighter PM line
