Is this too damaged by whatever bug got in there before I could saw it? I was going to use it for an 8x8 beam.

if that's pretty much the bulk of the damage in your photo, i wouldn't worry about it personally. albeit not knowing what your intention is for use beyond being a beam hard to make that call unequivocally. suppose if you were really concerned, one could always epoxy the damage with a slow cure 2 part epoxy $:-\$

That drops it below any structural grade.

We've been talking about them in another thread;

For decorative purposes it might be ok. Looks like some other deterioration/softness in the upper right area of your photo? Usually insect damage like that goes along with other issues.

I'd be concerned about a heavy load or long span.

The other concern is what else is growing up in the wood? Maybe it would eat more, or maybe it would decide to come out and have a family reunion / feast on the rest of your new building. Kinda look like they may be bee holes.

I doubt bee holes. The link that Don P posted is my bet.
Now if I needed a 2x6 and that was a 2X10 I might use it. But I would not use it for a 2x6. Eastern white pine is not strong too begin with. But I plan on using some for building. Most of my hemlock is gone. It will be thick stuff.

Thanks for all the replies, I wasn't getting notifications. I meant to take a pic of the worm today...fat white and about 1"long. Looks like some kind of larvae.

Pine borer, once you remove the bark and saw they're done for. I wouldn't use the one pictured for anything structural.

Fresh cut logs normally will not have these worm holes. When the pine lay around in spring or summer this [and blue stain] is what happens.
