Diptera
Diptera , or true flies, is the order of insects possessing only a single pair of wings on the mesothorax; the metathorax bears a pair of drumstick like structures called the halteres, the remnants of the hind wings. It is a large order, containing an estimated 240,000 species, although under half...

. He became the first North American specialist on this group, publishing over 50 dipterological publications and naming more than 1250 species. His best-known works were the three editions of the Manual of North American Diptera (1888, 1896, 1908).

Theories

Williston noticed that, over evolutionary time, the modular and serially repeated parts distinguishing animal groups exhibited trends in numbers and types. For instance, ancient vertebrates were characterized by mouths that contained mostly similar teeth, whereas recent vertebrates are characterized by mouths that contain many different teeth, adapted for biting, tearing, and compacting food; differences ultimately characterized different diets, with carnivores bearing incisors and canines and grazers bearing mostly molars. So pronounced were these trends that Williston (1914) declared that “it is also a law in evolution that the parts in an organism tend toward reduction in number, with the fewer parts greatly specialized in function”.
