ID Please, waterbug

[iturnrocks]

I collected this waterbug while dip netting a creek in SE Riley county Kansas this afternoon. although he doesnt look as ferocious as a predacious diving beetle, Im curious of what species it is and what it does eat.

Thank you,

This is a water scavenger beetle, in the family Hydrophilidae, genus Tropisternus. Cool find.

This is a webpage with picture of different beetles from the Family Hydrophilidae. It might be helpful? I just wanted to try to find something to point you in the right direction, us Kansasans need to look out for each other! haha!

Whoops, posted this too late.
