University of Alberta Entomology Collection
This site has some good pictures, but is lacking when it comes to mayflies.

Dale Parkers Aquatic Invert Guide for Saskatchewan
A great guide. I'd like to see something similar on this site someday.

Aquatic Invertebrates of Alberta
The Bible of Aquatic Bugs in Alberta... formerly out of print, you can now browse the whole text book on line!! The book may be a bit technical for the average flyfisher.

River Watch- How to monitor aquatic inverts
A good and basic guide with a quiz... targeting kids, but great for budding entomologists.

Canada's Freshwater Invertebrates
A university of Guelph site, with basic info on inverts... few pictures or keys.

Mayfly Central
This is the authority on Mayfly distribution in the Americas. Really just a list of where certain mayflies occur.

Dan Johnson's Grasshopper guide
from the University of Lethbridge.
Great info about grasshoppers...
He also has a great page on some Alberta Spiders

Iowa State Entomology Index of Internet Resources
A good compilation of info.
