Comment: One of the easier Donacaula species to identify. It is brownish-white or -pale yellow, darker towards the costa. There is a prominent dark streak (not dotted) from just above the dorsum at about two thirds and going straight into the apex of the wing. Unlike other Donacaula species, the female is similar to the male and does not have markedly more pointed wings. The male and female genitalia are quite different to other NA Donacaula species. Based on barcoding data there could be at least 5 separate species under this name.
