The Megapenthes comprises click beetles with distinctive morphological features, though specific details about this species remain poorly documented in accessible literature. Like other elaterids, possess the characteristic prosternal that enables the '' mechanism for righting themselves when overturned. The species is part of a genus distributed across North America, with typically developing in decaying wood or soil.
