Water-lily Reed Beetle
A metallic coppery-bronze aquatic beetle with longitudinal ridges on the elytra. Adults sit on floating leaves of pondweeds and bur-reeds in still or slow-flowing water.
Did You Know?
Larvae construct a silken cocoon underwater attached to plant roots, filling it with air obtained from the plant's tissues for pupation.

A tiny mayfly whose amber-colored spinners fall to the water in dense clouds. Nymphs live among fine sediments in slow-flowing water.

Spinner falls can be so dense they coat the water surface like a film, triggering frenzied fish feeding.
