Male and Female Crane Flies
Tipula bicornis / Diptera
May 11, 2007
Crane flies look like giant mosquitoes, but they do not bite. The female is the fly on the left, she has a thicker and more pointed abdomen. The male's abdomen has claspers for mating.
True flies are in the order Diptera, meaning "2-winged"; all other winged insects have 4 wings. Flies have small, knobbed vestigal wings called "halteres" which are used as stabilizers. The halteres are not visible on these insects.
True flies have the name "fly" as a second word, as opposed to a butterfly or dragonfly which are not flies.
