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.

Jargon Defined:

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.

Nymph: The juvenile, underwater stages of mayflies, stoneflies, dragonflies, and damselflies and other aquatic insects whose juvenile stages are covered by hard exoskeletons. The word can also refer to the fishing flies which imitate these creatures, in which case it is used as a blanket term for flies imitating any underwater stage of an invertebrate (except for crayfish and leeches).
