Naiads look more like crayfish or small crustaceans than winged insects.

Is Stonefly tolerant 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 are stoneflies predators?

Stoneflies, along with mayflies and caddisflies, are important biotic indicators of water quality. Stoneflies are subject to predation from larger invertebrate predators (e.g., hellgrammites) and fish.

Do mayflies fly?

The male grabs a passing female with its elongated front legs and the pair mate in flight. ... The male fly rarely returns to the water but instead he goes off to die on the nearby land.

Do stonefly nymphs swim?

After gathering gas under its exoskeleton, it tries to swim to the surface with an undulating motion of its body.

How do you identify a stonefly?

Stonefly larvae can be recognized by the presence of two claws at the end of each leg, wing pads in mature larvae, and an abdomen terminating in two long, segmented filaments. Characters such as wing pad shape, gill presence and location, and labium shape (Fig.

How do stoneflies mate?

In North America and Europe male and female stoneflies usually find one another by joining in mating swarms near streams and rivers. Males and females locate one another through a complex series of vibration signals known as drumming. ... Males transfer sperm directly to the female's reproductive organs during mating.
