A very rare species in Belgium.
Native
Wingspan 10–13 mm. Adults are very similar in appearance, but smaller than the commoner Pammene regiana, and the dorsal blotch in Pammene trauniana is more uniform in shape with the posterior edge square against the dorsum and tends to be paler, more lemon-yellow in colour.
A whitish larva with gray-brown dots, the head is light brown, the neck plate differs little from the body color, the rear is lined with dark dots, the anal valve is brown.
The larva lives in the seeds and its presence is indicated by an exudation of frass at the seed base. It vacates the seed in September when fully fed and hibernates in a silken cocoon spun under bark at the base of the host tree.
They fly during the day in bright sunshine around the top of the trees and later occasionally come to light.
The adults have been seen from late April towards early August.
The larva lives on Acer campestre.
It inhabits gardens, parkland, scrub, hedgerows and woodland.
