Physical Characteristics

Size varies from 2–33 mm long; metatibia slender with less than four teeth on the outer edges.

Distribution

Over 800 species worldwide; over 35% of the genera in the Americas, Australia, Madagascar, but less than 20% in Afro-Eurasian regions.

Diet

Primarily coprophagous (dung feeding), some feed on carrion or fungi, and smaller species may utilize leaf litter.

Life Cycle

Life cycle stages include egg, larva, pupa, and adult; specific life cycle details not provided.

Reproduction

Reproductive behaviors may vary by species; typically involve the utilization of dung or organic material for breeding.

Ecosystem Role

Key decomposers in their ecosystems, contributing to nutrient recycling by breaking down dung and decomposing materials.

Evolution

Thought to be derived from an ancient ball-rolling lineage, but phylogenetic validity of certain classifications has been questioned.

Misconceptions
