Distribution
North America: Canada (New Brunswick, Nova Scotia, Ontario, Prince Edward Island, Quebec) and USA (Connecticut, Iowa, Illinois, Indiana, Massachusetts, Michigan, North Carolina, Nebraska, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Wisconsin).
Behavior
Capable of gliding on water surfaces, a characteristic ability of Steninae . This is achieved through the production of specialized gland secretions that reduce surface tension, allowing rapid movement across water to escape or capture . Some Stenus also employ a unique prey capture mechanism involving eversion of mouthparts using blood pressure, with adhesive secretions from to secure small prey such as collembolans.
