The wingspan is about 13 mm. Adults are night active. The forewings are unicolorous, without spots or pattern.
The larvae feed on Agathis robusta. Young larvae probably bore in the cones of their host plant. Full grown larvae mine the seeds. They go into a very long diapauze. From caterpillars found in February 1964, a number had not pupated in April 1966 and even in September 1969.
