In northern Alabama the breeding of A. t. appears to be restricted to water holes in hollow trees and decaying stumps, as judged from many collections from tupelo gum ponds and other situations. This is apparently a 1-brooded species with some form present from early Mar. to the middle of July. The larval period varies from 20 to 50 days, the pupal period from 2 to 4 days and the adults live approx. 1 mo. The [female][female] bite readily during late spring. The food requirements seem to be general from studies made in 12 situations and from the examination of the gut contents of 21 larvae. These contents, listed respectively with remains appearing most frequently listed first, are amorphous brown matter, flagellate protozoa, fungous spores, soil particles, diatoms, blue green algae, pollen, filamentous green algae, non-filamentous green algae, ciliates and copepods. The larvae seem to ingest any particle that can be swept in. Larvae were found breeding with Culex apicalis, Theobaldia melanura and A. triseriatus.
