Small Amber Spinner
A tiny mayfly whose amber-colored spinners fall to the water in dense clouds. Nymphs live among fine sediments in slow-flowing water.
Did You Know?
Spinner falls can be so dense they coat the water surface like a film, triggering frenzied fish feeding.
Common Acerentomid
A tiny eyeless proturan found in forest soils across Europe. It walks on only four legs, holding its forelegs forward as antennae.
Did You Know?
Proturans are the only hexapods that add body segments as they molt, starting with nine abdominal segments and gaining three more.
