Crioceridae have an oblong body, and frequently enlarged pos- 

 terior femora (hence Eupoda of Latreille) ; many species are more 

 or less aquatic. The other families have mostly a rounded body 

 (Cyclica, Latr.), and are invariably terrestrial. They are all found 

 on plants, feeding principally on the leaves. In this group there 

 are over 10,000 described species.
