IMPORTANT. Genus and/or species of insects are continually being re-classified. The chart below was sent to me by a fly-fisherman in Washington State who states that "Early in my fly-fishing maturation, I developed a keen interest in aquatic entomology, and have pursued it, particularly since retirement, with a zeal my wife believes to be obsessive." I imagine that kind of good natured comment rings a bell with a lot of fly-fishermen.
The information was gathered from a fantastic site at The Integrated Taxonomic Information System (ITIS)

A major problem I have with the above site is that it does not seem to recognize commom names (or maybe I just don't know how to work the system).

The underlining indicates an error/correction in spelling.
The arrow -> indicates a change in taxonomic classification.
Yellow highlighting indicates a Genus and /or Species needing change.
Green highlighting indicates the corrected Genus and/or Species.
