Collection and habitat data.

Watrous (1981) reported Lobrathium grande  from a variety of riparian habitats. Adults occurred in moss roots, in leaf litter and sticks at a stream margin, in litter in a North American beaver ( Castor canadensis  Kuhl) lodge and in leaf litter at the margin of a swamp. Larvae were described by Watrous (1981). In New Brunswick, was adults were found in silver maple swamps, seasonally flooded marshes, a mixed forest, and beaver pond margins. Adults were usually found among moist leaves along pond and vernal pond margins or by treading vegetation in marshes. One individual was captured in a Lindgren funnel trap deployed in an old silver maple swamp. Adults were captured during April, May, June, July, and August.
