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) reported specimens from under bark of white pine in ON. According to Seevers (1978) 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). Brunke et al. (2012) reported Dexiogyia angustiventris  for the first time for Canada based on specimens from ON.
