Acorn weevil life cycle 2023

Periodically oak trees produce amazing crops of acorns in seasons called mast years. In addition to many birds and mammals, beetles called acorn weevils take advantage of the bounty. Female weevils deposit eggs inside acorns which hatch into larvae called grubs. Grubs develop during summer and escape in autumn through exit holes and enter the soil to pupate. A year or more later they emerge as adults and using jaws at the tips of their ridiculously long snout cut holes in acorns where the next batch of eggs are laid.

I make acorn flour as a hobby and supplement to three regular flour we buy, and these guys are the bane of my existence!

Do the adults eat the same food as the grubs?
