Grubs on Dining Room Floor are Acorn Weevil Larvae

“What is this worm that I keep finding on my dining room floor?” asks Stacey in her submission regarding the white worm pictured below. “We have looked and can’t find them anywhere, but all of a sudden we find them in the morning and we clean them up. And when we get home in the afternoon we find a couple more.” Based on the excellent photo Stacey sent in, we think she found an acorn weevil larva. Acorn weevils are brown beetles that bore holes through acorns to lay their eggs inside. Once they hatch, the larvae will eat the insides of the acorns until they fall from the tree, after which the larvae will bore a new hole through the acorns to exit from, and consequently tunnel into the soil to pupate (the process of metamorphosing into the adult insect).

The small white worms fall onto our reader’s car and truck, which are parked under an oak tree. The reader was first of all concerned with identifying what the small white worms on the oak tree are, but he was also keen to know where they are coming from. We address both concerns below.
