1/26/2024 0 Comments Acorn grubs![]() ![]() Nut weevil larvae eat the nutmeats of acorns, hickory, or other nuts, then bore out of the nut, drop to the ground, and live in the soil before pupating. Her snout is long and slender for this purpose. Larvae: If you slit open a stem lengthwise with a fine, sharp knife, you will see the borer larva, which has a fat, white, wrinkled body and brown head it can grow to about an inch long. For each egg, the female nut weevil bores a tiny hole into a developing acorn, hickory, or other nut. I have included a couple of links below to websites with photos and more information about the acorn weevil that might help determine if it is indeed this species. Eggs: The eggs are tiny, flat, oval, and brown.The eggs are laid around the bases of squash plants. If they are simply wandering in from outdoors, having tight-fitting screens, and sealing or caulking openings around doors, windows and vents will help prevent them from entering. If acorns are present, getting rid of them will eliminate the weevils. They can simply be vacuumed up as you find them. ![]() Whatever they are, these weevils are harmless and will do no damage to anything in the house. If no acorns, then I really can't tell what these weevils are without seeing an actual specimen, but their presence would most likely be due to them migrating indoors simply seeking a protected place to spend the winter. If acorns are present indoors, perhaps even stored in walls or attics by squirrels or birds, that is my best guess as to where these weevils might be coming from. But if acorns were brought indoors, the emerging larvae might just pupate near the acorns and then turn into the adults right away because of the warm temperatures. In the Fall after the acorns have dropped, the larvae normally leave the acorns and burrow into the soil to pupate and then turn into adults which emerge the following year. In this species, the adult weevils lay eggs on developing acorns in the summer, with the larvae developing inside. There are some other items in the photos which I can't identify, but look like they could be acorn caps. One of the first things you should craft with Grub Hide is a canteen, but other good recipes to craft with Grub Hide are a Mite Hat and Grub Vest. You must have a shovel, as this is how you dig up Grubs. This species is related to the plum curculio and other species which normally attack fruits and nuts of trees. Grub Hide is an item dropped by these underground creatures. If they are, the larvae of these weevils are known to develop inside oak acorns. Based on the overall shape and what little color patterns I can distinguish, I compared the photos to specimens in our collection and suspect these might be the acorn weevil, scientific name: Conotrachelus posticatus. The overwintering biology of the acorn weevil, Curculio glandium in southwestern Ontario. I can tell that these are NOT one of the stored product pest weevils, so they are either emerging from something else in the house or else they are "outdoor" weevils that have moved into the house seeking a place to overwinter. Unfortunately the photos aren't good enough to for me to be able to identify this weevil with any certainty. The insects in your photos are a type of weevil, Order Coleoptera, Family Curculionidae. ![]()
