Ovipositing Culex quinquefasciatus, photographed by Sean McCann.

Belongs within: Culicidae.

Culex is a large genus of mosquitoes, a number of species of which are significant disease vectors. Females of Culex species lay eggs in rafts of large numbers of eggs, up to 200 at a time. Larvae of the subgenus of Lutzia are predatory; members of this subgenus differ as adults from other Culex species in their high number of lower mesepimeral bristles, with four to six bristles present (versus at most two in other subgenera) (Liehne 1991). The acrostichal bristles (near the midline of the scutum) are well developed in members of the subgenera Culex and Neoculex but reduced in the subgenera Culiciomyia and Lophoceraomyia (Liehne 1991). Members of the subgenus Neoculex have bands of pale segments across the posterior margins of the abdominal tergites; these bands are basal on the segment or absent in the subgenus Culex (Stone 1981).

Characters (from Liehne 1991): Head with decumbent scales narrow, upright forked scales on vertex. Palps shorter than proboscis. Spiracular bristles absent. Lower mesepimeral bristles absent or few in number. Pleura largely bare with a few small patches of scales. Abdomen with segment VIII short and broad, cerci short. Tarsal claws simple, pulvilli present. Larva with antennal seta 1-A inserted beyond midpoint of antenna; prothoracic setae 1P to 7P usually long and branched, 1P to 3P set on distinct sclerotised plate; saddle completely rings anal segment; siphon long, pecten well developed, seta 1-S with several pairs of setae; anal segment with seta 3-X usually long and simple.
