This species is very variable. This forewing pattern is very similar to another image posted on the ALA:

Some of the variation is between the sexes. This is a female.

How do you tell the females from the males?

Spectrotrota fimbrialis males have a more bowed costa that b=gives them a more rounded shape at rest; they have a tuft of long loose scales near the base of the forewing; and an unscaled depression just inside the costa towards the base of the wing. The long labial palpi curve over the back of the head. 3390732 is a male (there are others)
