There are currently more than 460 recognized species of Ampedus beetles. It has a cosmopolitan distribution, but is found mostly in the Holarctic region, primarily in North America, Europe, and Asia. Ampedus beetles are primarily found in temperate forests, with a preference for higher altitudes. They are generalists, with a single species often found in both hardwood and softwood, and on multiple different tree species.

Ampedus larvae burrow in rotting wood, pupating in mid-summer. The larvae feed on wood, with a preference for wood in more advanced stages of decay, and are also observed to be preditating on other saproxylic larvae. They emerge as adults a few weeks later, but remain in the pupal cell through the following winter. Adult Ampedus beetles are thought to be diurnal. As adults, they are pollen-feeders, found in large numbers on flowers and vegetation.
