This beetle is native to the Nearctic, but today it can be found nearly worldwide; it is easily introduced to new areas.

[1] This beetle can be identified by two reddish bands on its elytra, black setae, and antennae tipped with clubs divided into four segments.

It feeds on dried animal products such as museum specimens.

All of these species have been moved to genus Eurhopalus, which is revised from taxa of Southern Hemisphere, many of which were previously considered to be Trogoderma.

[2] By definition of Zhou et al. (2022), the species is Eurhopalus vespulae, however the change is not yet accepted by some researchers.
