[1][2][3] Adult female Culex territans overwinter in protected, humid, underground environments like caves.

[9] Body temperature is not an important cue in host-seeking, which makes sense as their primary hosts are ectothermic.

[10] Since they mainly feed on frogs, they do not pose a direct threat to human health in terms of vectoring pathogens.

territans have been found to harbor various pathogens such as anuran trypanosomes, ranaviruses, and filarial worms.

[2] It has also been shown capable of mechanically transmitting the spores of chytrid fungus between frogs.
