Caterpillar
Whitish body with dark brown dots, the head is dark brown, the neck plate is the same color as the body, has dark edges on the sides and back, finely dotted in the middle, the anal valve is black at the front and black at the back whitish.
Bionomics
There is still a lot of uncertainty about how the larva lives. Literature states that the larva lives in hymenopteran galls or between leaves on the host plant. The larva build a cocoon into bark crevices, rotten wood, between dry leaves, in wood galls in late summer in which it hibernates and pupates.
The adults can sometimes be found on the wing in the afternoon and later come to light.
Flight periods
This is one of the earliest of the Olethreutinae to appear in Spring. The adults fly in one generation a year from late February till late April, occasionally later.
Observed on
- Host plant (genera):
- Quercus
