What order are stoneflies?
Stonefly, (order Plecoptera), any of about 2,000 species of insects, the adults of which have long antennae, weak, chewing mouthparts, and two pairs of membranous wings. The stonefly ranges in size from 6 to more than 60 mm (0.25 to 2.5 inches).
Can stoneflies bite?
Giant stoneflies are the largest stonefly species, with adults reaching nearly two inches long. Adults have no mouthparts so they do not eat or bite. As large and imposing-looking as giant stoneflies are, they’re completely harmless.
Are stoneflies sensitive to pollution?
Predacious stoneflies help to increase macroinvertebrate species diversity by feeding on true fly larvae. They are also one of the most pollution sensitive orders of aquatic insects. Along with caddisflies and mayflies, they are one of the three most commonly used indices of aquatic ecosystem health.
What animals eat stoneflies?
Common prey include chironomid midges, mayflies, caddisflies, and even small stoneflies. Stoneflies are subject to predation from larger invertebrate predators (e.g., hellgrammites) and fish.
How do I get rid of stoneflies?
Stoneflies cannot be controlled through treatments because they breed in aquatic environments and only become pests when attracted by outdoor lights to buildings. Any emergence of stoneflies, however, should last only a few days.
Do stoneflies fly?
Nymphs like giant stone flies live in the rivers for as long as three years before they hatch into winged adults. They are attractive to trout in several sizes, almost year round. As the stone fly nymphs grow they must take over a larger territory.
Do damselflies eat stoneflies?
Dragonflies and damselflies have a large, extendable lower “lip” (labium) that can engulf very large prey, with mature dragonflies sometimes eating small fish.
What does a stonefly nymph look like?
Stonefly larvae (also called nymphs or naiads) are aquatic, flattened, with 6 sprawling legs and with a segmented abdomen bearing 2 long antenna-like “tails” (cerci). Antennae are threadlike and long. Colors are usually dull, dark, and drab brown, yellow, or sometimes green.

What kind of flies are in the Capniidae?
The Capniidae, the small winter stoneflies, are a family of insects in the stonefly order (Plecoptera).
How big do Adult Capniidae Plecoptera get?
Adult Capniidae, as their common name implies, are typically small Plecoptera; while most are less than 1 cm long with some measuring just 4 mm as adults, a few are as large as 25 mm (1 in) at adulthood.
What kind of body does a winter stonefly have?
Nymphs of small winter stoneflies typically have very elongated and slender bodies, similar to those of Leuctridae. However, the groove along the abdomen, from segment 1 to 9, is generally very pronounced. The nymphs dwell in the hyporheic zone, the interface between stream water and groundwater.
Is the family Capniidae monotypic or a subfamily?
The family Capniidae is often considered to be monotypic as to subfamily, with the Capniinae being inserted at that rank. However, this is rather pointless; in any case, the phylogeny, systematics, and taxonomy of the small winter stoneflies are highly confused.
