The Tipulidae, commonly called ''Crane-flies", comprises one of 

 the largest families of Diptera, with some 8,500 described species, of 

 which nearly 500 occur in northeastern North America. The adult 

 flies frequent a variety of habitats, though usually not far from mois- 

 ture, required in one form or another by the larvae of all species. The 

 habitats of the immature stages have been briefly discussed under 

 the various genera. Students who are interested in the early stages of 

 these flies are referred to the following papers :
