Great silver water beetle — size comparison — facts and sources

The great silver water beetle depends on vegetated waters including ponds and ditches. It is large and black with an oval body and clubbed antennae. Ventral air films produce underwater silver sheen.

It regularly surfaces for air and can fly well despite aquatic life. Predatory larvae eat aquatic snails and leave characteristic shell marks.
