Lichenaula undulatella

Lichenaula undulatella is a moth in the Xyloryctidae family. It was described by Walker in 1864. It is found in Australia,^[1] where it has been recorded from New South Wales, Queensland and Western Australia.

The wingspan is 18-21 mm. The forewings are red-brown, becoming deeper on the lower half and there is a rather broad white streak along the costa from near the base to near the apex, attenuated to both extremities. A broad grey streak, sprinkled with brownish, is found along the inner margin from the base to the anal angle, beyond the middle forming a broad triangular projection upwards, reaching half across the wing, then abruptly attenuated. There is a darker transverse mark in the disc at two-thirds and a slender strongly outwards-curved whitish line from the costal streak at two-thirds to the inner margin before the anal angle, indented above the lower extremity, where it forms a small spot. There is also a grey apical blotch, covering the whole area beyond this line except a spot towards the anal angle and there is a series of small dark fuscous spots along the hindmargin and around the apex. The hindwings are fuscous, lighter and more ochreous-tinged anteriorly, the hindmargin suffusedly darker.

The larvae feed on Acacia decurrens, Acacia melanoxylon, Acacia pendula and Jacksonia scoparia. They bore in a plant gall or are found in a shelter in leaves or phyllodes.^[2]
