Eucosma ridingsana

Kearfott (1908) states

"This species is closer to ridingsana Rob. than any other of the silvery spotted Eucosma's; it can be separated by the median line, which in ridingsana is continuous from base to beyond middle of wing; the silvery costal streak, on inner half of wing (absent on male fold) of ridingsana is entirely absent in sandiego; the terminal line of dots of sandiego is also a distinguishing mark. There is a certain amount of variation in the spots of sandiego as in ridingsana, in fact in both species, seldom are the two wings replicas of each other. The occurrence of both sexes of both the brown and ochreous form is interesting and if there were not such uniformity in the spots and markings I would be inclined to think there were two races."

Note: The silvery costal streak, on inner half of wing mentioned by Kearfott (1908) as being absent in sandiego is present in the pinned photo by Todd M. Gilligan @ Moth Photographers Group.
