scientific name    Culiseta impatiens    

habitat
Larvae are found in semipermanent and shaded permanent ponds. Adults are widespread.

seasonality
Very early spring to late fall.

identification
Adult: ventral margin of anepisternum, anterodorsal angle of katepisternum, postspiracular area, and underside of paratergite all with patches of scales; tarsomeres almost entirely dark-scaled; wing-veins entirely dark-scaled, with weak aggregations of spots at the bases of Rs, R2, R3, and R4+5. Larva: antennae half as long as head capsule; siphon three times longer than greatest width; dorsolateral abdominal setae 1-VI and 1-VII multiple, and much shorter than other dorsolateral setae (appearing as small tufts), saddle setae fine and minute.

life history
Females overwinter as mated nullipars, and are one of the earliest emerging blood-feeders. Females are extremely longevid, surviving until late fall. Eggs are laid in rafts of about 100. There is only one generation per year. Males do not swarm, and mated pairs have been found on cave roofs.

conservation
Somewhat infrequently collected, but not uncommon.

Females are blood feeders.
