The spotted pine sawyer beetle is in the longhorn beetle genus. If you hang out around enough log landings you’re bound to see them. This one flew into my truck.

Be careful how you pick them up. They have strong mandibles and are happy to bite you.

They reproduce in dead and dying trees. Their larvae will bore into the log, thus reducing its value.

Pine Sawyer Grub, larva, larval

The larval form is a borer that damages the wood.

A log deck in the wood is a natural attractant for the beetles. If the logs sit in the woods too long the beetles will get into them.
