These wasps are very very small, about 5 millimeters at the most. In the first photo you can see it boring a hole into our barn. They seem to be destroying the structure in our barn. The wings are smoky, and it is black with yellow stripes. The antennae is quite think in comparison to its size. The second photo shows the sawdust that accumulates as the larva bores into the woods. Please help with ID.

Parancistrocerus pensylvanicus??
It is said to be a predator of Tortricid moths, but this seems to be boring into our barn. Any ideas?

Thanks Maria!
Emma, I think the wasp is feeding its larva. Do mealy worms bore into wood? What do you think?
Thanks Maria!
Emma, I think the wasp is feeding its larva in the hole, not a mealy bug. Mealy bugs usually don't bore into wood, too, right? Thanks for your help!
Yes mealy worms do turn into beetles.Here is a wikipedia link.

the name of th ebeetle is "Tenebrio molitor" which is a species of darkling beetle.
interesting atuff!
Maybe you could create another spotting with the mealy worms.
Nice action series
You are right that they do turn into some bug. I forgot which bug though. will have to research it!
Thanks Emma! I think it is going in to feed the larva inside the wood. Perhaps. I thought mealy worms turned into beetles.
is it trying to dig a nest? Nice pics. Looks like those are mealy worms?
