Bionomics

The larva lives inside the acorns or the nuts on the host plant. Frass is expelled from the entrance holes. When the nuts fall from the tree, the fully grown larva exits and makes a hibernation cocoon in the litter or under the tree bark, or into the moss of the trunks.
Especially the males are active in early morning and in the late afternoon. They come to light.
