Collection and habitat data.

Dendrophagus cygnaei was found in various forest types in New Brunswick, including hardwood forests, an old red oak ( Quercus rubra L.) forest, mixed forests, a red spruce ( Picea rubens Sarg.) forest, an old (180-year-old) red pine ( Pinus resinosa Ait.) forest, an old-growth northern hardwood forest, an old-growth white spruce ( Picea glauca (Moench) Voss) and balsam fir ( Abies balsamea (L.) Mill.) forest, and an old-growth eastern white cedar ( Thuja occidentalis L.) forest. Adults were collected from under bark of Populus and sugar maple ( Acer saccharum Marsh.). This species was commonly collected in Lindgren funnel traps at most sites where these traps were deployed. Adults were collected during April, May, June, and July.

Distribution in Canada and Alaska.

AK, BC, AB, MB, ON, QC, NB, NS ( Bousquet 1991; Majka 2008). The New Brunswick record of Dendrophagus cygnaei reported by Majka (2008) was based on a specimen collected by W. McIntosh from Saint John in June of a year predating 1910. The above records provide the first recent records of this species from the province.
