Diving Beetle larva (left) is the young stage of a big dark-brown beetle. Both the larva
and the adult live in water.
The larva is a
fierce predator with big curved jaws for catching other small animals. While it is still
small, it may be eaten by larger animals such as Sticklebacks. When it has grown enough to
almost become an adult, it can then turn the tables and may catch and eat our Stickleback
