Natural history.

Smetana (1995) reported Gabrius lysippus from wet moss on rocks at streams or along the margin of streams. This species was found in similar habitats in NB. Adults were collected by splashing exposed rocks covered with moss in the middle of a small rocky, cold river, and from moss and saturated moss on rocks in shaded brooks. One individual was found in a Carex hummock in a stream and one was caught in a Lindgren funnel trap in the canopy of a red oak. Small streams with moss-covered rocks were present at the latter site. Adults were collected in May and July.
