Eleodes is a genus of darkling beetles commonly known as pinacate beetles or desert stink beetles. They are endemic to western North America, with many species found in the Sonoran Desert. The name pinacate is Mexican Spanish, derived from the Nahuatl (Aztec) name for the insect, pinacatl, which translates as "black beetle".
The pinacate beetle is noted for its defensive tactic of standing on its head and squirting a noxious spray. This has earned it the additional names of clown bug and stink bug, names also applied to other unrelated insects.
