Many insects can be nuisances around swimming pools. Caddis flies, moths, and beetles are often attracted to lights around the water and many eventually fall in.
Aquatic insects fly to find water to live in.
Some aquatic bugs can inflict painful bites. They frequently attack animals larger than themselves and feed by sucking the body juices from their prey. A common method of capturing prey is to drift up under it after releasing hold of submerged plants to which they have been clinging. These insects will bite humans when handled, and the effect is much like a bee sting. Backswimmer eggs are deposited in the tissues or glued to the surface of aquatic plants.
