Catoryctis tricrena

Catoryctis tricrena is a moth in the family Xyloryctidae. It was described by Edward Meyrick in 1890. It is found in Australia,[1] where it has been recorded from South Australia, Victoria and Western Australia.

The wingspan is 20–21 mm. The forewings are fuscous with a white streak from the base immediately beneath the costa, reaching the costa at one-fourth, and continued along it to two-thirds, finely attenuated. There are one or two short whitish lines between the veins towards the costa posteriorly and a moderate straight white longitudinal median streak from the base to the apex, the posterior fourth cut by a longitudinal fuscous line. Three short white longitudinal lines are found between the veins towards the hindmargin and there is an ill-defined narrow whitish straight longitudinal streak from the base of the inner margin direct to the anal angle, posteriorly confluent with a fine whitish line along the submedian fold. The hindwings are grey.

The larvae feed on Casuarina species.[2]
