Maculated dung beetle (Aphodius distinctus) is a small aphodine dung beetle native to Europe, Asia, and Northern Africa. It was introduced into and is now common and widespread in North America. Adults are seen on cattle dung, often in large numbers, from March to May and again from August to October. Some evidence suggests that the larvae may be an agricultural pest, eating the roots of crop plants, but further study is needed to confirm this.
This species is identified by the elongated body; three projections at the tip of the antennae that can be tightly closed; variable yellow markings on the forewings; and keel-shaped ridges on the middle and hind legs.
