Probably braconinae
Not enough detail to know for sure. Many braconines oviposit into wood-boring insects, and Braconinae is a large subfamily of Braconidae. If I could see whether or not there is an occipital carina on the back of the head, I could be more certain.

Looks like....
A Brachonid of some sort. Perhaps something in the Atanycolus Genus?

?Brachonid wasp sp.
I thought Brachonid wasps were parasitoids of caterpillars, etc. I watched this wasp for 20 minutes laying eggs in the crevices of bark of a silver maple tree. That's what confused me. But then I suppose just because it's a Brachonid wasp doesn't mean it has to be a parasitoid.

Some Braconids parasitize wood-boring insects...
...so she could have been laying eggs in insects/tunnels in or under the bark.

Braconid wasp laying eggs
That makes sense that she could be laying eggs in insects/tunnels or under bark where wood-boring insects live. She did seem to be very particular about where she laid her eggs, as though seeking places where her host insects are residing.
