Onthophagus

Onthophagus is a large and diverse genus of beetles belonging to the family Scarabaeidae, commonly known as scarab beetles. This genus is characterized by its small to medium size and often robust, somewhat flattened bodies. Many species exhibit prominent horns or tubercles, particularly on the males, which are used in đấu tranh for mates or resources. The coloration of Onthophagus beetles can vary widely, ranging from dull browns and blacks to metallic greens, blues, and coppers.

These beetles are primarily coprophagous, meaning they feed on dung. They are crucial players in many ecosystems as dung decomposers, breaking down animal feces and returning nutrients to the soil. This ecological role is vital for pasture health and nutrient cycling. Onthophagus beetles typically excavate tunnels beneath dung pats, where they deposit their eggs and the larvae develop. Different species have specific preferences for the type of dung they utilize, contributing to niche partitioning within their communities.

The genus Onthophagus is found on every continent except Antarctica. Their distribution and abundance are influenced by the presence of suitable dung-producing animals and appropriate environmental conditions. Due to their importance in decomposition and their relatively easy collection, Onthophagus beetles have been extensively studied by entomologists, contributing significantly to our understanding of insect behavior, evolution, and ecology.
