Natural history.

Little is known about the biology of Aleochara rubricalis  . One specimen was reported from a mouse nest ( Klimaszewski 1984). In NB, specimens were collected in Lindgren funnel traps in an old black spruce ( Picea mariana  (Mill.) BSP) forest, an old-growth white spruce ( Picea glauca  (Moench) Voss) and balsam fir ( Abies balsamea  (L.) Mill.) forest, and an old balsam poplar ( Populus balsamifera  L.) stand near a river. One specimen was found among decaying mushrooms in a regenerating mixed forest. Adults were collected during May, June, and September.

Distribution in Canada and Alaska.

BC, ON, NB ( Klimaszewski 1984; Bousquet et al. 2013). Aleochara rubricalis  was previously known mainly from the west coast from BC south to CA and northern AZ, with one doubtful record from western ON ( Klimaszewski 1984). The records presented above indicate that this species is transcontinental in Canada.
