There was a threat a while ago about entomology and where you could find info on topic. Check out www.flyanglersonline.com. Look at the bottom of the home page for entomology section. Also very informative on tying and how to on fly fishing. Many many illustrated articles on tying various flies. Was killin time today and rediscovered the site. Terry
