Flies are virtually unique, because they have only front wings. The hind wings have become small, gyroscopic sense organs that stabilize flight by informing the insect if it yaws, pitches, or rolls.

Attempts to control salt marsh mosquitoes have included draining marshes and drenching them with insecticides, thereby damaging the marsh ecosystem—no small matter, because salt marshes are winter refuges for huge flocks of migrating ducks and geese and indispensable nurseries for the young of many marine animals, including blue crabs, shrimp, flounder, sea bass, bluefish, and others that are important in the human diet.
