Hatches Made Easy:

Needle Stoneflies - (Leuctridae Family)

05/05/08

Species of this 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.
Emergence is somewhat variable. We show them on our hatch charts hatching
from mid August all the way through the first week of December.

The following species have been found in the Great Smoky Mountains National
Park:
Leuctra alexanderi
Leuctra biloba
Leuctra carolinensis
