Needle Stonefly
A small slender stonefly that rolls its wings tightly around its body at rest, giving it a needle-like appearance. Common in small streams across Europe.
Did You Know?
Needle stoneflies are among the most pollution-sensitive aquatic insects and disappear quickly from streams affected by acid rain.
Large Stonefly

Large stonefly nymphs require three years to complete development, making them particularly vulnerable to long-term changes in water quality.
