What is the largest type of mosquito?
Toxorhynchites
Unlike Toxorhynchites mosquitoes, detritus feeder mosquitoe female larvae rely on blood meals to produce eggs more plentifully than a diet of nectar would permit. And even though blood sucking is a risky strategy that entails more casualties, and they could in principle subsist on nectar and the like as their males generally do, the risk is outweighed on average by the increase in the number and size of yolk-rich eggs that such protein-rich food permit.
