Natural history.

In SK, adults were captured from gilled mushrooms, dry and decaying mushrooms, old polypore fungus on dead lodgepole pine stump and on lodgepole pine. Elsewhere, adults of Silusa californica were collected from July through September by means of passive pitfall traps, Luminoc pit-light traps, Malaise traps and by sifting forest litter, wet moss on forest floor, marten dung on moss, and mushrooms ( Klimaszewski et al. 2003). Most specimens were captured in the passive pitfall traps. Adults occurred in coniferous (red spruce, Sitka spruce), mixed-wood (yellow birch/balsam fir), and unspecified deciduous forests ( Klimaszewski et al. 2003). The Alberta specimens were collected in boreal mixed-wood forest, predominantly trembling aspen with a small amount of eastern balsam poplar, white birch, white spruce, and willow species ( Klimaszewski et al. 2003). Five of the specimens were taken from old stands at least 100 years of age, nine were from mature stands 65 to 75 years of age, and three were from a recently harvested stand, 3 years of age ( Klimaszewski et al. 2003). The specimens from the Carmanah Valley, Vancouver Island, British Columbia, were mainly captured in the forest interior, followed by fewer in the transition zone, and only two specimens were found in the clear-cut zone ( Klimaszewski and Winchester 2002).
