Why didnt Noah swat those two mosquitoes?

Mosquito eggs are needed to feed crayfish, dragonflies and frogs. Flying mosquitoes are food for frogs, bats and birds, especially purple martins. In the bigger scheme of things, mosquitoes help keep ecosystems balanced by transmitting diseases. Diseased animals are easier for carnivores to capture and disease keeps the numbers of certain animals from getting too large for the food supply. That seems kind

of cold, but that is the way it is.

They probably are not too concerned with their usefulness to humans!
