Hex Mayflies
Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

This one pretty clearly keys to Kogotus, but it also looks fairly different from specimens I caught in the same creek about a month later in the year. With only one species of the genus known in Washington, I'm not sure about the answer to this ID.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

I'm hoping somebody can tell me what I'm dealing with here and possibly a proven imitation?Sorry,no pics,but I'll it describe best I can.

I beleive this caddis is some type of green sedge,but I can't find a pic of an adult to verify this,nor have I found a pattern that IMHO represents it very accurately?The entire bug is a beautiful bright,light green..more like lime or chartreuse,including the wings.Early June,midday,Southwestern New Brunswick,Canada.I've searched through hundreds of green caddis patterns on every flytying forum I can think of,and not a single green caddis imitation I've found has matching green wings like these naturals?Is this a standard practice to ignore the wing color?I'm sure natural colored elk/deer hair works as well,but it seems to me "matching the hatch" more accurately would only make sense?I'm not too bad at tying trout streamers and salmon flies sz 10 and larger,but I'm still a very amateur tier,esp. when it comes to sz 14 and smaller.I did manage to tie a reasonable imitation(basic elkhair caddis) with green dyed deer hair,and even lifted a few nice brookies with them.(patting self on back,LOL)

My questions are:
1)Is this a caddis unique to my area which might explain why I can't find any published imitation or do all/most green sedges also have green wings?
2)Or...is it common to ignore the wing color and tie it with natural colored elk?
3)Should I simply order a bunch of green elkhair caddis flies from a reputable tier or spend the rest of winter practicing tying the small stuff?

Greenghost-

You don't actually say what size it it, but if it's #16-#18, my guess would be Brachycentrus appalachia.

Greenghost,

Your description doesn't seem to match any caddisfly that I know (especially the green wing part), but it does sound exactly like the little chloroperlid stoneflies of Alloperla. These are commonly called Little Green Stoneflies or Lime Sallies and are often seen fluttering around riffled areas at midday in June. Compare to these images:
