Reed Beetle
A striking aquatic leaf beetle with metallic golden-green to coppery elytra and elongated hind legs. It is one of the largest European Donacia species, found on waterlily pads.
Did You Know?
Larvae live entirely underwater, tapping into plant roots for both food and oxygen, using specialized spiracles to breathe air from root aerenchyma.
Neotropical Backswimmer
A small aquatic bug that swims upside-down using its long oar-like hind legs. Its pale ventral surface provides camouflage when viewed from below against the sky.

It carries a silvery air bubble on its belly that functions like a physical gill, extracting dissolved oxygen from the water.
