Telephone-pole beetle

The telephone-pole beetle (Micromalthus debilis) is a beetle native to the eastern United States, and the only living representative of the otherwise extinct family Micromalthidae (i.e., a "living fossil"). Classification of M. debilis was historically controversial and unsettled. The species, first reported by LeConte in 1878, was long considered one of the Polyphaga, and placed in the Lymexylidae or Telegeusidae, or as a family within the Cantharoidea. However, characteristics of larvae, wings, and male genitalia show that it is in the suborder Archostemata, where it has been placed since 1999.
