predaceous diving beetle

Aucune description en français n’est encore disponible.

The Dytiscidae, from the Ancient Greek word δυτικός (dutikós), meaning "able to dive", are the predaceous diving beetles, a family of water beetles. They occur in virtually any freshwater habitat around the world, but a few species live in terrestrial habitats such as among leaf litter. The "diving" in their common name comes from their cycling between underwater and the surface to replenish oxygen like a diver.
