Habitat and breeding sites
The immature stages of Culex davisi were collected from bromeliads, Aechmea lindenii in Brazil. They were found with larvae of Toxorhynchites separatus, Ochlerotatus terrens, Haemagogus spegazzinii, Toxorhynchites theobaldi, Wyeomyia muehlensi, and Wyeomyia (Phoniomyia) sp. Females prefer to feed on birds. Stein et al. (2011, 2013) did not capture specimens of Microculex on chicken, rabbit or human bait, despite a large number of immature specimens found in nearby larval habitats. Lourenço-de-Oliveira & Heyden (1986) had the same results using horse, cow, sheep, and frog bait and classified these species as hematophagous on ectothermal animals.
