What kind of acorns does the acorn weevil prefer?

Answer 1

Black [Quercus kelloggii, Quercus velutina], red [Quercus rubra, Quercus falcata] and white oak [Quercus alba] trees are the sources of the acorns that the acorn weevil [Curculio glandium] prefers. That's because these acorns provide good shelter for the female weevil's eggs and good food sources for the larvae into which the eggs hatch. Once the nutmeat has been eaten and the larvae gone, these vacant acorns still have uses for other wildlife. Specifically, acorn moth caterpillars, fruit flies, and fungus gnats use the insides as temporary shelters. In fact, they all enter and exit by the holes that the acorn weevils first drill with the sharp jaws at the end of their long snouts.
