Anecdata: we had a crazy spring in New Hampshire for the mosquito population. It was extraordinarily uncomfortable to spend any time outside during May / June.

Anecdata: we had a crazy spring in New Hampshire for the mosquito population. It was extraordinarily uncomfortable to spend any time outside during May / June. Over these past few weeks, their populations seem to have plummeted near my house, making it quite enjoyable during the evenings now. The only difference is the appearance of two enormous bald-faced hornet nests in some nearby (but not too nearby) trees. I couldn't find any explicit mention of mosquitoes in their diet, but they do seem to have an appetite for all kinds of insects.
