Does diving beetle back-swimmer and water boatman eat the same food?

Diving beetles, back-swimmers, and water boatmen all inhabit aquatic environments, but their diets differ. Diving beetles are primarily predators that feed on other aquatic organisms, including insects and small fish. Back-swimmers also consume small prey but are known for their unique ability to swim upside down and can eat other insects on the water's surface. Water boatmen, on the other hand, primarily feed on algae and plant matter, although they may occasionally consume small invertebrates.
