Yes, diving beetles are considered to be omnivores. This means they eat foods of both the plant and the animal origin.
They will eat any non venom insect such as upside down beetles flys (do not feed it any type of ants) the especialy like moths and gold fish (they only eat goldfish when they are the right size) i have a great diving beetle as a pet and i feed it every day also great diving beetles will eat each other and for mating they are kinda like a pray mantis they beetle shows of in the water and if the female does not like it the female eats its head and great diving beetles will also eat turtle pelets and sea food such as (siclid food and just regular fish food)

no water beetles do not eat tadpoles because i have a little water beetle that swims with tadpoles every day in my dads wheel barrow if u are wondering why i have a tadpole in a wheel barrow its because the pond at the the back of my house dryed up and he/she was iin it so i saved itall the rest are little frogs and the are starting to jump away so theres ur answer they dont eat tadpoles :)
Because so many of the tadpoles never make it to adult hood - many animals eat tadpoles and young frogs, such as birds, fish and diving beetles.
small fishes................
cormorants are a diving bird and will eat most fish
