Needle Stonefly
Introduction:
(Leuctridae Family of Stoneflies)

Species of the Leuctridae family of stoneflies are fairly easy to identify as adults because their
wings roll around their bodies. This gives them a “needle-like” appearance. These stoneflies are
usually called “Needle Flies” and sometimes “Black Roll Wing Stoneflies”.They are very small, slim,
dark stoneflies.

They are often confused with caddisflies. They resemble caddisflies in flight. In fact it is very
difficult to tell them from caddisflies without catching one. When you do you will see the difference
very quickly. It is just the way they fly, especially when the females are depositing their eggs, that
makes them look like larger caddisflies depositing their eggs.

Emergence is somewhat variable. We show them on our hatch charts hatching from mid August all
the way through the first week of December depending on the stream. There are a lot of species,
all of which look very similar. They are easy to distinguish from other stoneflies because of their
long bodies.

These stoneflies are very plentiful in Great Smoky Mountains National Park. Trout eat the nymphs
and the egg laying adults as well as any other species of stonefly. Until we found them, identified
them and listed them on our hatch charts, I never heard anyone that fishes the Smokies mention
them. I think most anglers thought they were a caddisfly due to their resembles of them when they
are flying.

We developed an imitation of the little nymphs and the adult and I will be writing them within the
next couple of days.

Here is a list of the species, which are very difficult to tell apart, that have been officially found in
the park.

Here is where they have been found.
