Ochlerotatus sticticus

(Meigen, 1838)

Ochlerotatus sticticus is a floodwater mosquito native to the Palearctic region, with established in Europe and northern Asia. It is a member of the floodwater mosquito group, characterized by that can withstand desiccation and hatch when inundated by rainfall or flooding. The species exhibits distinct physiological and behavioral responses to larval drying that differ from co-occurring floodwater species such as Aedes vexans, suggesting specialized adaptations to temporary aquatic environments.

Identification

Distinguishable from similar floodwater mosquitoes through genetic and morphological analysis; belongs to the Ochlerotatus group within Culicidae. Specific diagnostic features for field identification are not detailed in available sources.

Habitat

Floodwater and temporary aquatic environments subject to periodic drying and inundation. Larvae develop in standing water that forms after rainfall or flooding events in otherwise dry depressions.

Distribution

Europe and northern Asia (excluding China); North America; southern Asia. Present in Belgium and the Flemish Region.

Diet

Females require blood meals for development; males and non-gravid females feed on nectar and other sources.

Life Cycle

are deposited in dry floodplain soils and can withstand desiccation until inundated by water. Larval development occurs in temporary aquatic . Specific details on larval instar duration, , and timing are not documented in available sources.

Behavior

Exhibits -specific responses to larval drying that differ from Aedes vexans, suggesting adaptive strategies for survival in ephemeral aquatic environments.

Similar Taxa

  • Aedes vexansCo-occurring floodwater mosquito with which O. sticticus is frequently compared in ecological studies; both species share floodwater preferences but differ in larval responses to habitat drying.
