Natural history.

Specimens were collected during June by treading emergent Carex into water in a Carex marsh along a lake margin and in a Carex marsh near a small stream. The specimen from ON was captured in a yellow pan trap near a sewage lagoon in June. Campbell (1983) reported this species from similar habitats elsewhere in its range.
