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.[1]

E. caryochroa larvae are leafminers and favour low growing plants in damp or estuary grassland habitat.[5]
