scientific name    Culiseta morsitans    

Larvae are found in a variety of shaded natural water bodies. Adults tend to associate.

Spring to mid or late summer.

Pleural areas largely devoid of scales except for a few post-spiracular scales; abdominal tergites banded or patched only basally with pale scales; scutal inegument dark brown; aedeagus distinctly diamond-shaped, pointed at the apex. Larva: very difficult to distinguish from C. minnesotae. Antennae as long as head capsule; antennal seta 1-A inserted in the distal third, with branches extending beyond the tip of the antenna; siphon six times longer than greatest width or longer; pecten teeth of the siphon larger than minnesotae; head setae 5-C and 7-C usually with fewer than 6 and 9 branches respectively, seta 4-X (ventral brush) of anal segment generally with 18 or fewer setae.

life history
Unlike most other members of the genus, Culiseta morsitans overwinters in the egg stage. Larvae emerge early in spring, usually in small temporary pools. Adults emerge in late spring and mate. Females lay eggs in rafts above the surface of the water on a moist substrate. Females are extremely longevid, producing up to 3 batches of eggs. The species is believed to be univoltine.

Unknown. Relatively uncommon in Alberta.

diet info
Females are blood feeders, preferring birds.

Likely throughout Alberta. Found throughout most of Canada and Alaska, and the northern states.
