It seems that for the time being I have lost my Caddisfly book by Gary LaFontaine and will have to suspend my Entomology research with regards to the Caddisflies in my area until I can either find it or find a replacement. With that in mind I felt it important to still continue to learn more about that which I am ignorant and the world of Midge’s as I found is a large one indeed. After doing a bit of searching I found a good general Midge resource at Westfly.com
The Westfly page has information on all varieties of Midges and how to best represent them and present them to trout. One thing I found interesting is that Midge larva hang suspended in the water and that your fly should try to mimic that behavior so perhaps a very lightly weighted fly on just the head might help. The Westfly page also has several articles on how to tie various midge patterns and how to best present those patterns under different conditions. This should be used only as a general resource though, I know I will be going to find out what my water holds first hand, hopefully soon.
If the general resource doesn’t cut it for you, it didn’t for me I went further and happened to find a gem which happens to have been researched and produced in Minnesota. It turns out there is a Chironomidae Research Group associated with the University of Minnesota. Clicking a few links I found myself looking at A Guide to Aquatic Invertebrates of the Upper Midwest! I’m going to have to get my hands on a copy of this baby. For now though they have conveniently put sections of it on the web in PDF format. The Chapter on Midges is only 24 pages long and provides a guide to specific identification and information for several varieties of Diptera.
Click on the individual chapter you wish to look at and in a short moment a large amount of great information is at your fingertips. Chapter 13 deals with Diptera the two winged general genre that Midges fall into.
