I do not profess to know a lot about aquatic insects. Most of what you find here is taken from my field notes and they are vague at best. If you think some important insects are left out, let me know. If you feel some of the dates are wrong, let me know. I offer this is a very informal, very amateur chart, and will welcome upgrades.
