Title: What big is this?
Post by: forrestM on August 23, 2021, 07:32:33 PM
It's on eastern white pine. It has been a little over a month since it was cut. I thought they were going deep in the log but they seem to be active just under the bark which is a relief. They are so loud you can hear them chew as you walk by. Big piles of long skinny frass.

You dont show entry and exit holes, but most likely powder post beetle.  what I see in pic is larvae.  Need an actually adult to really know for sure.  Powder post live about 1/4" below surface.

Pine sawyer beetle larvae, at least I think, that's what i got eating under the bark in my
White pine logs anyway, and yes you can hear them! Crunch crunch

X2 on likely pine sawyer. Powderpost typically goes for the starchy sapwood of dry hardwoods and has fine frass. Have you seen longhorn beetles crawling around the pile?

Them things always make a point of landing on me, I will see it coming towards me and will back away and the buggers will circle around the yard with me trying to land in my shoulder or head  >:(   smiley_thumbsdown

Logyards should probably all have chickens around to control these little turds.  Theyre always just under the bark for me.

I also agree...larvae from pine sawyer beetle.
