Eucnemidae

Closely related to the family Elateridae, specimens of Eucnemidae can reach a length of {{convert|2|-|30|mm|abbr=on}}. Bodies are slightly flattened and convex. The upper surfaces of the body usually has hairs, setae or scales.

The larvae are typically legless, and generally develop feeding on the fluids of rotting wood, likely vomiting digestive enzymes into the wood to break apart the fungal hyphae, moving using their shovel shaped heads to force apart the wood. Adults, which are typically found on broken surfaces of trunks and stumps, have a short lifespan and it is unclear whether they feed, though they are capable fliers, and like some other elateroids are capable of clicking.Muona, Jyrki.
