Collection localities in New Brunswick, Canada of Batrisodes frontalis . Collection and habitat data. Batrisodes speciesare usually found in leaf litter, rotten wood on the forest floor, or in ant nests amongst the ants, particularly beneath the bark of conifers ( Chandler 2000 ). They are known to be predators or scavengers on mites, earthworms, and the brood of ants ( Park 1947 ). Batrisodes frontalis has been reported from beneath bark in the nests of three species of Lasius ants ( Wickham 1898 , 1900 ; Park 1947 ). All specimens from New Brunswick were captured in Lindgren funnel traps deployed in a mature hardwood forest, an old red oak forest, an old silver maple forest, a 110-year-old red spruce forest, and an old red pine forest. Adults were captured during June, July, and August. Distribution in Canada and Alaska. AB, MB, ON, QC, NB ( Davies 1991 ).
