Here is a bark beetle gallery, also called "bug trails", or "worm patterns in wood" on a tree branch of, most likely, a ponderosa pine. These patterns are caused by the larvae of bark beetles. The photo was taken on June 13, 2021 at the Lefthand OHV area of Boulder County, Colorado.

Equipment used: Canon EOS Rebel T5i with a standard zoom lens (EF-S 18-55 mm).
