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.
Tsetse Fly (Forest)
A major vector of African trypanosomiasis (sleeping sickness). Unique among flies for giving live birth to a single large larva nourished internally with a milk-like substance.
Did You Know?
The tsetse fly nourishes its single developing larva with a milk gland — this is the closest any insect comes to mammalian lactation and pregnancy.
