Map 2. Collection localities in New Brunswick, Canada of Euplectus confluens . Collection and habitat data. Park et al. (1950) reported Euplectus confluens from a sugar maple ( Acer saccharum Marsh.) tree hole. According to Wagner (1975) ,the preferred habitat of this species was loose, moist, decayed woody debris in hollow trees and basal tree holes in American beech ( Fagus grandifolia Ehrh.) and sugar maple. Wagner (1975) considered this species to be the most frequently collected Euplectus species in eastern deciduous forests. Chandler (1997) reported that this species was most commonly found in tree holes and rotten wood, but was also taken from barn debris and sawdust and at an ultraviolet light. In New Brunswick, adults were captured in Lindgren funnel traps deployed in an old red oak ( Quercus rubra L.) forest, an old silver maple ( Acer saccharinum L.) swamp, and an old mixed forest. Basal tree holes were frequent in the red oak and the mixed forest stand. Adults were captured during June, July, and August. Distribution in Canada and Alaska. QC, NB ( Davies 1991 ).
