Imitating Aquatic Insects -
Stoneflies
Stoneflies
Everyone loves to fish the larger, easy to see and easy to identify stonefly imitations. Presented correctly, at
the right time and place, stonefly imitations can account for some of the largest trout taken. The stonefly
nymph and adult stages of all the important species of stoneflies life cycles are covered. It includes scenes
from stonefly hatches most anglers have never witnessed. All the proven techniques that bring success in
imitating these flies are demonstrated in this fly fishing video.

Of the various stages of the stonefly’s life, the nymph is most important. By far, more stonefly, nymphs are eaten by trout than the full, grown adults. Most of all, in terms of
importance, is the presentation of the stonefly nymph. Generally speaking, if you are fishing on or very near the bottom, you are fishing correctly. If not, it may not matter at
all how close the imitation is, you are probably not going to do well at all. This fly fishing dvd shows you how to go about catching trout on imitations of both stages of life.

Genus: Isoperla:
S 801 Yellow Sally
The Isoperla genus contains two species that are very important. The bilineata species is called the “Yellow Sally”. It is a clinger nymph that lives one year. It prefers slow to
medium currents. It has yellow wings and a yellow body.

Nymphs crawl to the shoreline and crawl out on the banks to emerge. This migration from their locations in the riffles and runs to the shore is the time they are most subject to
being eaten by a trout. The trout may key in on this migration prior to a large hatch of stoneflies and position themselves nearer the banks than they normally do in any given
stream. This means that the best time to fish the nymphs are prior to hatch although trout can be taken to some degree year round on nymphs.
The adults mate on the ground and vegetation on the shore, not in the air like most other aquatic insects. During the day, stoneflies tend to stay hidden under leaves and limbs of
streamside vegetation. They are generally not available to trout until they begin their eggs laying process. Most species dip their abdomens into the water to lay their eggs,
although some species may crawl into the water to lay their eggs and other laid them above the surface of the water. The eggs laying process usually occurs most often just
before dark.
The adults, like the nymphs, vary greatly in size and color. The shapes are all about the same, with a few exceptions. This means that often you can get by with attractor or
suggestive imitations of the adults as long as the size and color are close. Specific or imitative patterns will probably work best in most cases, however.

Genus: Isogenoides:
Another example of the "Yellow Sally" is the genus, Isogenoides, which includes three species that can be important. The olivaceus species is commonly called the “Olive Stone”
and sometimes a “Yellow Sally”. The nymph is a clinger that lives for a year. It prefers slow to medium current. It hatches in the middle of the day. Olive Stones have a yellowish-
brown body with gray wings.
