No systematic work has been done in this genus, hence it is impossible 

 to present a comprehensive list. It is certain that all species recorded 

 from the eastern States will also occur in New Jersey, as well as many 

 more not yet discovered. Careful breeding through a series of years 

 will lengthen our list to over one hundred. As many of the species in 

 the adult stage are indistinguishable from each other, the only reliable 

 way to identify them is by breeding. 



The larvse are all case-makers, the cases distinctive for each species. 

 In shape they range from slender flattened cylinders to one made of 

 clusters of flowers. Almost every plant supports one or more species, 

 many are confined to grasses and others live in seed-heads.
