A crane fly is any member of the dipteran superfamily Tipuloidea, which contains the living families Cylindrotomidae, Limoniidae, Pediciidae and Tipulidae, as well as several extinct families. "Winter crane flies", members of the family Trichoceridae, are sufficiently different from the typical crane flies of Tipuloidea to be excluded from the superfamily Tipuloidea, and are placed as their sister group within Tipulomorpha.
The classification of crane flies has been varied in the past, with some or all of these families treated as subfamilies,[1] but the following classification is currently accepted.[2][3][4][5][6] (Species counts are approximate, and vary over time.)[4]
In colloquial speech, crane flies are known as mosquito hawks or "skeeter-eaters", though they do not actually prey on adult mosquitos or other insects.[7][8] They are also sometimes called "daddy longlegs",[7] a name which is also used for arachnids of the family Pholcidae and the order Opiliones. The larvae of crane flies are known commonly as leatherjackets.[7]
Crane flies first appeared during the Middle Triassic, around 245 million years ago, making them one of the oldest known groups of flies,[9] and are found worldwide, though individual species usually have limited ranges. They are most diverse in the tropics but are also common in northern latitudes and high elevations.[10]
More than 15,500 species and over 500 genera of crane flies have been described, the majority by Charles Paul Alexander, who published descriptions of 10,890 new species and subspecies, and 256 new genera and subgenera over a period of 71 years, from 1910 to 1981.[4][11]
