Cangetta ammochroa is a moth in the family Crambidae. It was described by Turner in 1915. It is found in Australia, where it has been recorded from the Northern Territory.[1]
The wingspan is about 10 mm. The forewings are pale-brown, with a costal fuscous streak and two brown transverse lines, as well as four or five brown-fuscous dots on the apical half of the termen, edged by a narrow whitish shade. The hindwings are as the forewings, but without the first line and with a line from the costa forming a V-shaped curve in the disc and ending on the dorsum near the tornus. Adults have been recorded on wing in January.[2]
