Catoryctis subnexella

Catoryctis subnexella 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 the Australian Capital Territory, New South Wales, South Australia and Tasmania.

The wingspan is 16-23 mm. The forewings are fuscous, more or less ochreous-tinged and with a white attenuated streak immediately beneath the costa, from the base to the middle. All veins tend to be marked posteriorly with whitish streaks, but generally very indistinct. There is a moderate straight silvery-white longitudinal median streak from the base to the apex, interrupted by a very oblique line of ground-colour before the middle, the lower edge emitting one or two short very oblique teeth on the veins posteriorly. Sometimes, there is a small darker spot on the lower margin of this at two-thirds and a slender whitish longitudinal streak from the inner margin at one-fourth to beyond the middle, often almost entirely obsolete. The hindwings fuscous or grey, becoming lighter and sometimes ochreous-tinged towards the base.

The larvae feed on Casuarina species.^[2]
