Disease relations: the species was found naturally infected with Plasmodium falciparum in eastern Colombia and with Plasmodium vivax in Venezuela (Moreno et al., 2005) and susceptible to the experimental infection with Plasmodium vivax (Simons, 1936)

Immature stages develop in water accumulated in tracks, tire marks, cattle footprints, with full exposure to the sun. Larvae have been reported in temporary pools (Stein et al., 2011), in the edges of woods that had marshy areas, typical of cattle pasture (Dantur Juri et al., 2011), as well as artificial breeding sites such as disused swimming pools (Díaz Nieto et al., 2020). They can tolerate dirty water with cattle feces (Komp, 1942). Larvae were collected together with Nyssorhynchus argyritarsis, Anopheles argentinus and Culex maxi larvae from natural and artificial breeding sites such as side-pools of rivers and disused swimming pools (Díaz Nieto et al., 2020). As for females, it has been mentioned that they are highly anthropophilic (Moreno et al., 2005), are generally captured and their hematophagous activity is recorded during the early hours of the afternoon. Females have been collected in the border of the forest, with marshy areas where cattle graze. The species could play a role as a secondary vector of Malaria, it is eventually incriminated in malaria transmission in forest areas recently occupied by humans.
