Collection and habitat data.

Adults of Calopus angustus were collected in various forest types in New Brunswick, including hardwood forests with sugar maple ( Acer saccharum Marsh.), American beech ( Fagus grandifolia Ehrh.), eastern white cedar ( Thuja occidentalis L.), an old-growth northern hardwood forest (white spruce, eastern white cedar, and balsam fir present), an old-growth eastern white cedar swamp, mixed forests, an old-growth white spruce and balsam fir forest, and an old red pine forest. Most adults were captured in Lindgren funnel traps. Some were also captured at an ultraviolet light. In western North America, Burke (1906) reared this species from a gallery of a living western cedar ( Thuja plicata Don ex D. Don) and found larvae and pupae in dead and living branches of alpine fir ( Abies lasiocarpa (Hook) Nutt.). This species probably uses related host trees, such as eastern white cedar and balsam fir, in our region. Adults were collected during April, May, and June, but most between late April and mid May.

Distribution in Canada and Alaska.

BC, AB, ON, QC, NB, NS ( Campbell 1991e; Majka and Langor 2011). Majka and Langor (2011) reported this species for the first time for New Brunswick from one locality in Madawaska Co (East Iroquois River) and two localities in York Co. (Fredericton and Charters Settlement). This species is widespread and locally common in the province.
