chloroperlidae
Green stoneflies are fascinating little insects that live in clean, cool streams. They have a special talent for helping keep the water healthy and clean!
Habitat: Freshwater streams and rivers with clean, cool water.
Appearance
The Green Stoneflies has a slender body, often bright green or yellowish-green, with long antennae and two pairs of delicate, membranous wings that fold flat over their back. Their color helps them blend into streamside vegetation, making them tricky to spot near water.

Special abilities
Ability
Bio-Indicator Vision
Green Stoneflies can only thrive in very clean, oxygen-rich water, helping scientists know if a stream is healthy.
Ability
Gilled Survival
Green Stonefly nymphs have gills on their bodies to breathe underwater, allowing them to live for years beneath the surface.
Ability
Nimble Nymphs
Green Stonefly nymphs can move quickly over rocks or burrow into sediment, helping them avoid predators in fast-flowing water.
Ability
Pulsing Messages
Some Green Stoneflies use drumming vibrations on surfaces to find mates, helping them communicate in noisy stream environments.
