An. triannulatus is commonly are found in lakes, ponds or large ground pools. An. triannulatus is clearly shown often to be closely associated with a specific plant; it is usually collected in or between the rosette crowns of Pistia stratiotes Linnaeus. Triannulatus adults are usually collected in the interior of forests, although the larvae may be collected from ground pools in interspersed secondary growth areas. (Faran and Linthicum 1981:8)

Medical Importance:
An. triannulatus doesn't seem to be an important vector of malaria. This species was implicated as a possible vector during an epidemic at a boys’ school near Maracay, Venezuela (Benarroch 1931), and once was found to have a natural oocyst infection (Gabaldon and Cova Garcia 1946b). Several investigators have experimentally infected triannulatus with Plasmodium vivax (Grassia and Feletti) and P. falciparum (Welch); however, it is much more refractory to infection than albimanus.
