Collection and habitat data.

In New Brunswick, most adults of this species were collected along river margins. Adults were collected from flood debris and drift material (maple seeds), and from under a cobblestone. Two adults were collected with an aerial net during an evening flight (16:00-18:00 h) along a river margin, and two individuals were collected from leaf litter at the base of a tree in mature hardwood forest (0.5 km from a river margin) during late April when some snow was still present. This may have been an overwintering site. Adults were collected during April, May, June, and July.
