Stenus
Guides
Stenus angustus
Stenus angustus is a rove beetle in the subfamily Steninae, known for their specialized adaptations for life near water. Members of the genus Stenus exhibit a range of water-gliding abilities, with some species capable of skimming across water surfaces using gland secretions that reduce surface tension. This species is documented from North America, with records from both Canada and the United States.
Stenus annularis
Stenus annularis is a species of rove beetle in the subfamily Steninae, described by Erichson in 1840. The genus Stenus is notable for its members' ability to glide on water surfaces using specialized gland secretions that reduce surface tension. Some species in this genus also employ a unique hunting mechanism involving the ejection of mouthparts using blood pressure to capture small invertebrate prey. Stenus annularis has a broad distribution across North America, with records from Canada and the United States.
Stenus latissimus
Stenus latissimus is a species of rove beetle in the subfamily Steninae, first described by Bernhauer in 1938. Members of the genus Stenus are known for their specialized hunting adaptations, including the ability to eject mouthparts using blood pressure to capture prey. The species has a transcontinental distribution spanning northern Asia and western North America. As with other Steninae, it is a specialist predator of small invertebrates.
Stenus latissimus hatchi
Stenus latissimus hatchi is a subspecies of rove beetle in the family Staphylinidae, subfamily Steninae. Like other members of the genus Stenus, it possesses the specialized labial apparatus that allows some species to capture prey using adhesive secretions. The subspecies occurs across a broad transcontinental range spanning northern Eurasia and western North America. As a member of the Steninae, it is associated with moist habitats near water bodies where the water-gliding behavior characteristic of many congeners may be expressed.
Stenus pinguis
Stenus pinguis is a species of rove beetle in the subfamily Steninae, first described by Casey in 1884. The species belongs to a genus renowned for its remarkable water-gliding ability, enabled by specialized gland secretions that reduce surface tension. As a member of Stenus, it likely employs the characteristic labial prey-capture mechanism using eversible mouthparts with adhesive paraglossae to capture small invertebrate prey. The species has been recorded across western North America from Canada to the United States.
