Collection and habitat data.

Brunke et al. (2011) noted that almost nothing was known about this rarely collected species but mentioned that it shared morphological features with other Staphylinidae living in subcortical habitats. Most adults of Habrocerus magnus from New Brunswick were found under somewhat loose bark of white pine ( Pinus strobus L.) (large logs and a large, dead, standing tree). One individual was collected from under bark of a large red pine stump. These data suggest that this species lives under bark of large dead conifers. Adults were collected during May, June, and August.
