Hellula undalis (Cabbage Webworm)

Adult moths have fawn forewings, each with sinuous pale lines and a kidney-shaped mark.

Hellula undalis can be separated from similar species by the shape of the post medial (white) line. Starting at the inner margin it runs across the wing for a short distance before forming a wide arc adjacent to the reniform mark,  then flattens out and widens to end at the costa.

The hindwings are a uniform grey darkening at the margins. The wingspan is about 2 cms.
