Ochlerotatus trivittatus

(Coquillett, 1902)

Ochlerotatus trivittatus is a mosquito in the , originally described by Coquillett in 1902 as Culex trivittatus. It belongs to the Ochlerotatus Group, a clade of related mosquitoes found in the Americas. The species has been documented across North America, Middle America, and South America. Genetic studies have examined its relationship to other Ochlerotatus Group species to clarify species boundaries within this taxonomically complex group.

Identification

Morphological identification relies on established for the Ochlerotatus Group. of the c oxidase subunit I gene has been used to confirm identifications and distinguish O. trivittatus from related including O. condolescens, O. infirmatus, O. thelcter, O. tortilis, and O. scapularis. Genetic analysis shows sufficient divergence from these relatives to support its status as a distinct species.

Distribution

North America, Middle America, and South America. Documented presence in the United States including Vermont.

Taxonomic History

Originally described as Culex trivittatus by Coquillett in 1902, later transferred to Aedes, and currently placed in Ochlerotatus following subgeneric elevation. The epithet 'trivittatus' refers to three stripes or , likely describing a pattern on the mosquito.

Genetic Research Context

O. trivittatus has been included in phylogenetic studies of the Ochlerotatus Group to resolve boundaries and verify morphological identifications. These studies used both c oxidase subunit I and internal transcribed spacer 2 gene sequences.
