Predaceous diving beetles swim by moving their hind legs simultaneously like a frog; which differentiates them from the similar looking water scavenger beetles (family Hydrophilidae), who move their hind legs alternately. The adults sometimes leave the water at night to fly to other water bodies. While flying they are often attracted to lights. The larvae are sometimes called water tigers. |
