(Caloptilia insidia)
Caloptilia insidia is a moth of the family Gracillariidae, one of the most primitive groups of ditrysian "micromoths". Within its family, it belongs to the subfamily Gracillariinae. It is apparently endemic to Fatu Hiva and Hiva Oa in the Marquesas Islands, French Polynesia. It is very similar (and presumably closely related) to C. deltanthes. The species does not seem to be common, and no females appear to have been encountered yet.
