Acorn Update

Red oak acorns need to be stored in a cool place for a month or so before planting. so I stored the acorns in a plastic bag in the beer fridge cooler.
Larva found of  Acorn Weevil
Much to my dismay, I found many larvae at the bottom of the fridge which tweaked my curiousity. It turns out that even though the acorns were selected many were still contaminated by eggs and the emerging larvae of the Acorn Weevil [Curculio glandium.] Apparently the larvae fall to the bottom of the bag and then chew their way through the plastic thus ending up at the bottom of the fridge. In nature they fall to the ground and then bury into the earth. I found that many of the acorns had the typical exit holes. So I will have to sort the good from the bad acorns one more time.
