Predaceous Diving Beetle

Freshwater environments such as ponds, lakes, marshes, and occasionally swimming pools.

Carnivorous. Adults and larvae (water tigers) eat aquatic insects, tadpoles, and small fish.

Excellent swimmers that carry an air bubble under their wing covers to breathe underwater. They are often attracted to artificial lights at night.

Benefits the ecosystem by controlling mosquito populations; larger species can deliver a painful (though non-toxic) bite to humans if handled.
