Collection and habitat data
Most adults from New Brunswick were collected from dried polypore fungi, partially dried Pleurotus sp., or other polypore fungi on logs or standing dead trees in mixed and hardwood (silver maple, sugar maple, and beech) forests. One individual was collected from under bark of a conifer stump in late November. This was probably an overwintering site. Adults were collected during May, June, July, August, September, and November.
Distribution in Canada and Alaska
BC, AB, MB, ON, QC, NB, NS (Bousquet and Campbell 1991; Majka et al. 2008). Platydema americanum Laporte and Brullé was reported from New Brunswick in Bousquet and Campbell (1991). However, no voucher specimens could be located to support this record, but Majka et al. (2008) provisionally retained the species on the New Brunswick faunal list. The above records confirm the presence of this species in New Brunswick. This species was reported by Majka et al. (2008) from one locality in Nova Scotia.
