Stenus plicipennis
(Casey, 1884)
Stenus plicipennis is a of rove beetle in the Steninae, described by Casey in 1884. Like other members of the Stenus, it possesses the characteristic labial apparatus used for prey capture, though the specific of this species remains poorly documented. The species has a Holarctic distribution, occurring across northern North America and eastern Russia. It represents one of numerous Stenus species adapted to moist microhabitats where predatory specialization on small occurs.
