I logged into Trout Nut recently because someone asked me for good resources for aquatic insects. Well, when I did, I noticed that the site looked different than I remembered.
I looked it over a little and the coolest (in my opinion) new thing is the new Streamside Feild Guide. Here I just put in a date (my birthday) and Ohio for the state. It brings up a seasonal guide of what insects I might see on the river during that time of the year. You can select from several species of insects and also select from nymphs, duns, adults, etc. Super easy and helpful!
