What is causing these holes anyone know?
Just on this one frame and it's a robust hive.

I would say they came that way, looks like carpenter ants that were in the tree when harvested.

Thanks! There was a hive beetle in one, so I didn't know if they could do that or not.

In addition to what GG said is the Hoverfly that is particularly fond of laying their eggs on downed pine.

At least around here, Greater Waxworm larvae will tunnel through frames in much the same manner as the photos you posted.

They will sometimes be on the side or bottom bars, but are most often in the corners where top and sidebars meet and through the topbar as shown in your photos.

Again around here, when put back in a strong colony they will often propolize the holes shut, so the frames are almost as good as new.

Thank you!
Smart ones they are☺

Do they also make the shallow oval 'pockets' under their cocoons? All I have seen and no actual through holes like in the pictures above. Distinction between greater and lessor waxworm?

That's what I observe- Greater will tunnel through. Lesser will dish out.

Thanks odfrank, Good to know,
If anything was alive in them they are no longer, I took a stick and jabbed into the bottom of them all rigorously! I did smoosh up a hive beetle.

That is a classic sign of beetle damage. If you look you'll see the frass lining the tunnels, and there's a beetle pupa in the top tunnel. I wouldn't worry about it as I've seen the, as well.

Happened to find a frame previously damaged by wax moth larvae for photo comparison when doing some winter wrap-up this afternoon.
