Wyeomyia Theobald, 1901



Generic abbreviation: Wy.

Type species: Wyeomyia grayii Theobald

Etymology: unknown [not stated]

Wyeomyia species are found in forested regions of the Neotropics, eastern United States, and on islands in the Caribbean. Wyeomyia most closely resemble mosquitoes in the genera Sabethes and Limatus but the presence of prealar setae differentiate Wyeomyia species from all other Sabethines, with the exception of Sabethes petrocchiae (Shannon & del Ponte). The genus was recently subdivided into 17 subgenera, following morphological and allozyme studies. The subgenera include Antunesmyia (3 species), Caenomyiella (1 species), Cruzmyia (4 species), Decamyia (3 species), Dendromyia (6 species), Dodecamyia (one species), Exallomyia (three species), Hystatomyia (9 species), Menolepis (1 species), Miamyia (7 species), Nunezia (3 species), Phoniomyia (22 species), Prosopolepis (1 species), Spilonympha (7 species), Triamyia (2 species), Wyeomyia (35 species) and Zinzala (2 species). Thirty more species remain unplaced.

All Wyeomyia DNA sequences




Wyeomyia are most commonly encountered in Neotropical forests where immatures occupy natural containers including bamboo (broken, internodes and stumps), tree holes, pitcher plants, bromeliad and aroid leaf axils, flower bracts, and the occasional artificial container. Immatures of the most northern Wyeomyia species—Wy. (Wyo.) smithii (Coquillett)are restricted to the acidic sphagnum bogs in the eastern United States where their host pitcher plants (Sarracenia purpurea gibbosa and Sarracenia purpurea venosa) are found. Larvae are sustained by the insect detritus-rich pitcher plant juices, and protect themselves from predation by a co-existing carnivorous chironomid by having long setae all over its body. Wyeomyia smithii overwinters as larvae and can tolerate freezing; adult females are autogenous.


Adult Wyeomyia are active during the day and at all elevations in the forest. Many feed readily on people, and many mammal and bird species. All Sabethine mosquitoes rest with their hind legs bent over the head, but Wy. smithii females maintain this stance even during flight.
