Natural history.

In NB, adults of Stenus destitutus were found along clear, cold, fast-flowing river and stream margins. Most specimens were collected by splashing exposed rocks with moss in the middle of a river or splashing emergent Carex hummocks within streams. One specimen was found among gravel and cobblestones near water. Adults were collected in May, July, and August.
