Larva trails under pine bark

Larva trails under pine bark
Groton, Middlesex County, Massachusetts, USA

Are these markings distinctive for a certain type of larva?

Moved

Ips?

Bark beetles
Scolytid galleries. Sometimes the patterns are distinctive enough to place to species.

 
Buprestid, too?
Looks like the scolytids crossed paths (literally!) with a buprestid or cerambycid larva, too (the broader meanderings). If you know the kind of tree the bark came off of, you can probably at least get a genus on these scolytid galleries.

 
scolytids and company
That's quite a design they make. Thanks for identifying it for me, Brad and Eric!
