The life history and immature stages are incompletely known; the egg and first instar larva are described by McGuffin (1972). Adults come to light. Handfield (1999) states that this is a species of open, mesic woodlands and bogs, but it in Alberta it occurs in much drier habitats. Perhaps more than one species is included under this name.
