Culiseta alaskaensis

Freshwater Invertebrate Collection

SeasonalityMay – July. IdentificationAdult: ventral margin of anepisternum, anterodorsal angle of katepisternum, postspiracular area, and underside of paratergite all with patches of scales; second and third tarsomeres with white bands occupying one quarter or more of each segment; hypostigmal area scaled; wing scales aggregated into spots at base of Rs and at R2+3 and R4+5, costa subcosta and radius with scattered white scales, crossveins scaled. Larva: antennae half as long as head capsule; siphon three times longer than greatest width; dorsolateral abdominal setae 1-VI and 1-VII usually double, saddle setae fine and minute, prothoracic setae 1-P single; antennae with coarse spicules.

Culiseta inornata

Freshwater Invertebrate Collection

SeasonalityEarly spring to late fall. One of the last mosquitoes present in fall. IdentificationAdult: ventral margin of anepisternum, anterodorsal angle of katepisternum, postspiracular area, and underside of paratergite all with patches of scales; tarsomeres dark-scaled; costa, sub-costa and radius with numerous scattered yellow scales; tarsomeres with pale yellow scales; wing scales not aggregated into spots. Palpus of male with terminal segment inflated, largely lacking setae. Larva: antennae half as long as head capsule; siphon three times longer than greatest width; dorsolateral abdominal setae 1-VI and 1-VII usually triple; saddle setae 1-X as long or longer than saddle, usually single.

Culiseta minnesotae

Freshwater Invertebrate Collection

SeasonalityMay to mid or late summer. IdentificationPleural areas largely devoid of scales except for a few post-spiracular scales; abdominal tergites banded or patched basally and apically with pale scales; scutal integument reddish-brown; aedeagus sub-parallel sided, broadly rounded or truncate. Larva: very difficult to distinguish from C. morsitans. 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 small; head setae 5-C and 7-C usually with more than 6 and 8 branches respectively, seta 4-X (ventral brush) of anal segment generally with 20 or more setae.

Culiseta morsitans

Freshwater Invertebrate Collection

SeasonalitySpring to mid or late summer. IdentificationPleural 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.
