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.

Female Skwala curvata (Large Springfly) Stonefly AdultFemale Skwala curvata (Large Springfly) Stonefly Adult View 2 PicturesThis female dropped her eggs just before this photo was snapped. The distinctive notch in the subgenital plate identifies the species. An interesting observation is how active they get when exposed to direct sunlight. Trying to stage this specimen was most difficult. In the shade it would calm right down, but when exposed to direct sun it would immediately go nuts, scampering all over quickly without pause. Perhaps this explains why they don't seem to be found out and about on overcast days, but if the sun peeks out... She was 24 mm long, head to wingtip.
