notes

The larvae reach a considerable size. Unfortunately it is not possible to specifically identify the larvae inhabiting acorns. Acorns play an important role as food for jays and squirrels, not in the least as winter cache. It has been shown that for these animals parasitised acorns are unattractive, despite their higher nutritious value.
