Xylorycta heliomacula

Xylorycta heliomacula is a moth in the family Xyloryctidae. It was described by Oswald Bertram Lower in 1894. It is found in Australia,[1] where it has been recorded from New South Wales, Queensland and the Northern Territory.[2]

The wingspan is about 27 mm. The forewings are dark fuscous, purple shining and with yellow markings. There is an elongate spot immediately beneath the costa at one-third and an irregular quadrate spot immediately beneath on the inner margin before the middle, as well as a large irregular ovate spot just before the apex, beneath which is a smaller spot suffused with three or four lines of ground colour. The hindwings are orange yellow with a narrow fuscous hindmarginal band, broadest at the anal angle.

The larvae feed on Amyema species and Grevillea striata. They bore in the stem of their host plant.[3]
