Carex rostrata & Co.). Dispersal abilities: Macropterous, probably capable of flight; swift
runners, excellent swimmers and divers. Seasonal occurrence: Adults have been found in
February – December; teneral adults in mid-September. Behavior: Adults are mostly diurnal,

dead vegetation, and in leaf litter. Adults were found overwintering under the loose bark of
trees, over 1 km from their breeding habitat.
