Not in Louisiana. However, the tadpoles of some toad species in other parts of the world are carnivorous and probably consume mosquito larvae. Unfortunately, most birds have already gone to bed when mosquitoes go to work. In New Orleans, the purple martins probably catch the most mosquitoes. Other swallows also catch flying mosquitoes and ducks consume lots of mosquito larvae.
Bats are the perfect flying-insect catching machines.
They go to work when night-flying insects such as mosquitoes are in the air. A single bat can catch as many as six hundred mosquitoes in an hour. The greater New Orleans area is lucky to be home to at least six species of bats. A very popular tourist attraction in Austin, Texas is a bridge where nearly one million bats roost during the day and then emerge at night to consume flying insects. They are called crane flies.
