Ozognathus cornutus is a species of beetle in the family Ptinidae.

[1][2][3] It is native to North America but has spread elsewhere, including Europe, North Africa, New Zealand, and South America.

[4] This beetle is saproxylophagous, meaning that it feeds on dead wood, including galls and the feces of other wood-eating insects.

[5] Adult Ozognathus cornutus are dark brown or black and 1.5-2.8 mm in length.

[4] They lay their eggs in galls induced by other species of insects.
