Wild poplulations of Aedes taeniorhynchus were polymorphic for the diets required for ovarian development. In Aedes taeniorhynchus populations from mangrove swamps, most females possessed the capacity to produce eggs on a blood-free diet. But where the grassy salt marsh was the mosquito's principal habitat,most females lacked this capacity. Both kinds of females could utiliZe a blood meal for egg production.
