Collection and habitat data.

Batrisodes riparius was reported from an ant ( Aphaenogaster ) nest by Park (1947), and has been taken beneath bark, from tree holes, and from rotten wood by fallen trees ( Chandler 1997). Specimens from New Brunswick were captured in Lindgren funnel traps deployed in a mature hardwood forest, an old red oak forest, and an old red pine forest. Adults were collected during June, July, and August.
