Collection and habitat data.

Bousquet (1989) reported that Henotiderus occur in leaf litter, and various fungi such as Polyporus , Pleurotus and Fomes in forests. Most specimens of Henotiderus centromaculatus from Nova Scotia were found in red spruce forests ( Majka and Langor 2010). In New Brunswick, this species was found in various of forest types including mature hardwood forests, an old red oak forest, an old mixed forest, mature red spruce forests, an old red (180-year-old) pine forest, an old-growth white spruce and balsam fir forest (boreal forest), and eastern white cedar forests. Adults were found under bark of a fungus-covered beech log, under bark of a Populus log, under bark of a red spruce, near slime mold under bark of Populus sp., and in fleshy (shelf) polypore fungi on an American beech log. This species was frequently captured in Lindgren funnel traps. Adults were captured during April, May, June, and July.
