Just wondering......... aren’t mosquito larvae a major food source for the baby fish in the everglades?
Yes, but there are PLENTY of native mosquito species in Florida.
If a pond has fish in it, there will not be many mosquitoes produced in that pond. As you say, the fish will eat the wigglers or larvae.
They really are prodcued by mud puddles or any standing water which has no fish in it. I forget the details but they can live and I think reproduce in high grass.
