Predaceous diving beetles are most commonly found  in slow moving bodies of water such as streams, marshes, pools, small lakes, and ponds. They would not likely be found in bigger bodies of water any rivers with a fast moving current or any type of ocean.

Their larva form, known as a "water tiger" is found on land as well, generally in forests under leaves, rocks, or other plants. 

Unfortunately, the biggest threat to the diving beetles habitat is pollution caused by us humans. These beetles are a vital component to any ecosystem and without them in the environment the entire food chain would get disrupted.
