Tipuloidea
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. Two other families of flies, the phantom crane flies ( Ptychopteridae) and primitive crane flies ( Tanyderidae), have similar common names due their similar appearance, but they are not closely related to true crane flies. The classification of crane flies has been varied in the past, with some or all of these families treated as subfamilies, but the following classification is currently accepted. Species counts are approximate, and vary over time. ; Infraorder Tipulomorpha : Superfamily Tipuloidea (Typical Crane Flies) :: Family Cylindrotomidae (Cy ...

Limoniidae
Limoniidae is the largest of four crane fly families, with more than 10,700 species in more than 150 genera. Some studies have suggested it to be a paraphyletic group, with some limoniids being more closely related to Tipulidae and Cylindrotomidae than to other limoniids. Limoniid crane flies can usually be distinguished by the way the wings are held at rest. Limoniids usually hold/fold the wings along the back of the body, whereas other crane flies usually hold them out at right angles. Snow flies (genus: ''Chionea'') such as ''Chionea scita'' have no wings at all. Limoniids are also usually smaller than other crane flies, with some exceptions. The classification of Limoniid crane flies has been varied in the past, with the group treated both as subfamily and family, but the following classification is currently accepted. (Species counts are approximate, and vary over time.). Recent phylogenetic analyses have revealed the family to be paraphyletic and further research is suggeste ...
