* it's hard to imagine how any predator could specialize in adult
Mosquitoes, with their strategy of clinging to vegetation until a
potential host comes by, and they spend such a short time as adults
that no parasitoid could benefit from them. The infrequency with which
one sees Dragonflies of Bats exploiting the cloud of Mosquitoes one
attracts oneself emphasises the effectiveness of their cling-and-wait
strategy.
