Natural history
Specimens of Dexiogyia angustiventris from NB were caught in Lindgren funnel traps in a hardwood forest in the canopy of Populus tremuloides, an old red pine forest, and in an open field and meadow. One individual was collected from Tricholomopsis platyphylla (Pers.) Sing., on a log in an old-growth sugar maple and yellow birch forest and another from under bark of red spruce in a mature red spruce stand. Brunke et al. (2012)[1] reported specimens from under bark of white pine in ON. According to Seevers (1978)[2] Dexiogyia is associated with subcortical microhabitats, particularly pine, and occurs in burrows of wood-boring Coleoptera.
Distribution in Canada and Alaska
ON, NB (Bousquet et al. 2013[3]). Brunke et al. (2012)[1] reported Dexiogyia angustiventris for the first time for Canada based on specimens from ON.
