Natural history.

The SK specimens were found in pine clearcut, on recently dead white spruce, and in moss and pine litter in May, June and September. Elsewhere, specimens were collected from under bark of logs, from leaf litter, flood debris and wet moss, from soil along a stream, from fungus ( Fomitopsis pinicola, Fomes robineae), and from a squirrel midden (Hoebeke 1985).
