Finding Ecdyonurus nymphs means the river water is super clean and healthy!
Some Ecdyonurus adults live for only a few hours to find a mate!
Ecdyonurus nymphs can cling tightly to rocks in fast-flowing water because of their flattened bodies and strong claws, which helps them avoid being washed away.
Ecdyonurus nymphs can breathe underwater using specialized plate-like gills along their abdomen, allowing them to live in oxygen-rich streams.
Ecdyonurus has a unique pre-adult flying stage called a subimago, which molts again into a true adult after leaving the water.
Young Ecdyonurus munch on tiny plant bits and algae from river rocks!
