basic bug identification on stream

Monticello, NY Posts: 504	Hi; I was wondering if someone could give me some tips/pointers on basic id'ing. for the 1st several yrs I flyfished, I ignored that aspect fo the sport and focused on casting, rigging, knots, etc. Know that i'm more proficient in those other areas, I want to get better at id'ing the bugs! I'm sure i can tell caddis from mayflies and spinnersIin most cases) from duns but its hard for me to sort out the nymphs. Example, yesterday, me and a buddy went fishing and he pointed out to me all the empty Iso shucks from the nymphs emerging. When I looked at them, the color looked right(sorta brownish red?)but honestly, they kinda looked like stoneflies as well. Any easy way to tell the difference? Thanks, Adirman

Isonychia nymphs will appear to have one wingcase (they have a second to house the smaller hindwings, but it is hidden under the first) and three (fringed) tails. Although Isonychia nymphs have rather long antennae for a mayfly, they are not as conspicuous as most stonefly antennae. As a general guide to some of the easily observable differences, this link to Roger's website should help: http://www.flyfishingentomology.com/Aquatic%20Insect%20Recognition.htm
