Isogenoides hansoni (Appalachian Springfly) Stonefly NymphIsogenoides hansoni (Appalachian Springfly) Stonefly Nymph View 11 PicturesThis large Perlodidae stonefly was a strikingly bright yellow color, more so than any other insect I've seen. I didn't enhance it much. See the discussion threads to follow how we identified this specimen, which was listed incorrectly for several years.

Female Amphinemura (Tiny Winter Blacks) Stonefly AdultFemale Amphinemura (Tiny Winter Blacks) Stonefly Adult View 5 PicturesA few of these tiny stoneflies were among the only species of aquatic insect adults in the air on this particular afternoon, with most of the action coming from a species of Epeorus mayfly. I somehow forgot to photograph this one on the usual ruler, but I recall it was very, very small, with an abdomen no more than 1mm in girth and the body, not counting the wings, probably just 5-7mm long.

Paragnetina (Golden Stones) Stonefly AdultParagnetina (Golden Stones) Stonefly Adult View 10 PicturesUnfortunately I forgot to photograph this one next to the ruler, but I seem to remember it being on the small side for a Perlid, maybe around 2cm.

Isoperla (Stripetails and Yellow Stones) Stonefly AdultIsoperla (Stripetails and Yellow Stones) Stonefly Adult View 10 PicturesSeveral stoneflies of this species were flying around a small stream last night. I tied on a brown drake imitation of about the right size/color to approximate these stones, and was rewarded with a hard-fighting 17-inch brown trout.
