Descriptions of Nearctic Caddis Flies (Trichoptera), with Special Reference to the Illinois Species

This paper, describing new species of caddis flies from Illinois and other localities in North America, is the initial report on a project of the Illinois Natural History Survey pertaining to these aquatic insects. A complete report treating of the Illinois fauna is planned tor later publication. This latter, more comprehensive faunistic study will be fashioned after some recent Survey reports on insect groups and will include keys to the adults and larvae, illustrations of the diagnostic characters, and data on the biology and distribution of these insects occuring in Illinois. The role of these insects in the economy of our lakes and streams makes their study of special interest.published or submitted for publicationis peer reviewe
