Little Green Stonefly:
The “Little Green Stonefly” adults (“Chloroerlidae”) are very similar to the “Little
Yellow” stoneflies. In fact, contrary to what the name indicates, the “Little Green
Stoneflies” are sometimes almost yellow. They are small to medium sized
stoneflies that emerge in the spring and summer months. Although they are
never any super hatches, the long emergence period of anywhere from thirty to
sixty days, makes this family important.
The adults vary from a very bright green to a yellow color. All of them have short
tails. Like most stoneflies, cold mountain streams are an excellent habitat for the
Little Green Stoneflies
.
The Haploperla brevis, a LIttle Green Stonefly, is often called a
“Little Yellow Stonefly”, Yellow Sally, and sometimes, the “Wee Yellow” Stonefly”.
I mention it separately because it is often confused with the Little Yellows. It is a
small yellow-green winged fly with a green body. The nymph is a clinger that
lives just under one year. They do not hatch in a consistent manner, so it is not
really known as to when you should expect to encounter them.
