Donacaula mucronella §1 male
ID: similar to D.forficella. D.mucronella can be distinguished by the presence of a sharply demarcated pale costal streak and the absence of a dark diagonal apical streak. Pleurota bicostella (Oecophoridae) has a similar forewing pattern but can be distinguished by the presence of 2 or 3 discal dots in the forewing and a narrow ascending S3 of the labial palps.
