Consider, for example, a small, delicate, blood-sucking mosquito; an innocuous, longlegged crane fly, sometimes mistaken for a gigantic mosquito; a nectar-drinking drone fly, a convincing mimic of a honey bee; or the large, stout-bodied, blood-sucking horse flies such as the “greenies” that plague bathers on New Jersey beaches. 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.

Commenting on a manuscript version of this book, Ann Downer-Hazell of Harvard University Press wrote: “The ‘smoke’ cloud of mosquitoes anecdote is something out of a horror film. But great—I love it. Once my husband and I were sitting inside a cabin in Maine watching a ball of mosquitoes mill around just outside. ’” Mosquitoes are persistent, but not that persistent. 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.
