Eutorna caryochroa

Description

Eutorna caryochroa is a species of moth in the Depressariidae family. It was described by Edward Meyrick in 1889. It is endemic to New Zealand. The wingspan is 11–12 mm. The forewings are rather dark ferruginous brown with an upwards-curved yellowish-white streak from the middle of the base to two-thirds of the disc, margined beneath with blackish, above with bright yellow ochreous, which extends to the costa towards the base. There is a slender white oblique streak from two-thirds of the costa to the middle of the disc, margining a triangular costal suffused patch of purplish-grey and whitish scales, beneath which is sometimes a longitudinal blackish suffusion. A black dot is found in the disc at two-thirds, surrounded by a yellowish-white ring. There are some purplish-grey scales towards the posterior half of the inner margin and a small white spot on the costa at four-fifths, beyond which is a blackish suffusion. There is also an obscure irregular whitish streak along the hindmargin, followed by some black scales. The hindwings are rather dark bronzy fuscous. E. caryochroa larvae are leafminers and favour low growing plants in damp or estuary grassland habitat.
