Roachflies
This common name refers to only one family.
Stonefly Family Peltoperlidae
These are very rarely called Roachflies.
These stoneflies, known for their roach-like shape, are not really mentioned in books about angling. They are a major component of the invertebrate fauna in a few streams, which are presumably few and far between. Since their robust shape is so distinct, I speculate that a special nymph pattern would pay off on the rare waters where they are major insects.
Tallaperla (Roachflies) Stonefly Nymph
View 6 PicturesThis is the first specimen of the Peltoperlidae stonefly family that I've collected. It's very small and probably an early instar (Instar: Many invertebrates molt through dozens of progressively larger and better-developed stages as they grow. Each of these stages is known as an instar. Hard-bodied nymphs typically molt through more instars than soft-bodied larvae.), but I'm not choosy about new bugs.
