What it looks like: 2.5-3.3 mm in length. Its body is oval and reddish-brown. It has short, clubbed antennae and long, thin legs. It has unique striae, rows of shallow punctures on the elytra (wing coverings) that run transversely instead of lengthwise, as they do in most beetles.

Where you'll find it: This species can be found throughout the western United States, southern Canada, and northern Mexico.

Natural History: These beetles generally live in the nests and burrows of small rodents like marmots and pocket gophers. They have also been found in burrowing owl nests.
