Collection and habitat data.

Nycteus testaceus was collected from gilled mushrooms on the forest floor of a hardwood forest, and at an ultraviolet light in a mixed forest and a hardwood forest. One individual was captured in a Lindgren funnel trap deployed in an old red oak forest. This species was capable of jumping out of a 15 cm high sifting box, resulting in the loss of a number of specimens collected from gilled mushrooms. Adults were captured during July, August, and September.

Distribution in Canada and Alaska.

NT, BC, AB, SK, MB, ON, QC, NB ( Campbell 1991a). Campbell (1991a) reported this species from New Brunswick. However, Majka (2010) could not find any specimens or published source to support the record and, therefore, considered the status of this species in the province as hypothetical. The above records confirm the presence of this species for New Brunswick.
