Collection and habitat data.

Watrous (1980) reported Lathrobium confusum from the margin of an intermittent stream. In New Brunswick, adults were found in leaf litter or grass litter near small brooks and streams and in leaf litter along vernal pond and forest pool margins. Some were sifted from leaf litter at the base of large silver maples or from litter in the crotch of a silver maple with multiple trunks. Adults were found in mixed forests, silver maple swamps, red maple ( Acer rubrum L.) swamps, and an alder ( Alnus sp.) swamp with red maple. This species was collected during April, May, and June.
