Euconnus rasus
Euconnus rasus is a minute rove beetle in the subfamily Scydmaeninae, first described by John Lawrence LeConte in 1852. Members of this genus are among the smallest beetles, typically measuring under 2 mm. The species has been recorded across northeastern North America, with scattered observations in the Great Lakes region and Atlantic coastal states. Like other scydmaenines, it likely inhabits leaf litter and other decaying organic matter, though specific ecological details remain poorly documented.
