The conspicuous and harmless Rhinoceros Beetle male is a large and easily recognizable beetle that doesn't let its fame go to its head.
The male Rhinoceros beetle is best identified by the presence of a long, black horn protruding from its head. This horn is used to keep other males away from a female. Females do not have a horn. The rounded pronotum is large. Both sexes have faint ridges on the black elytra. Dark red hairs stick out from under flake-like extensions on their legs. While larger than most beetles, Rhinoceros Beetles are smaller than the Eastern Hercules Beetle with its own pincer-like horns on the head.
Rhinoceros Beetles are not known to bite and are considered somewhat friendly. Adults may eat dead roots. and larvae are believed to feed on dead and decaying plant matter on the forest floor. This particular species of Rhinoceros Beetles is found in woodlands west of the Rocky Mountains. Ash tree roots are a favored food source for larvae. Adults are mostly active at night and may be attracted to lights.
