Carnivores
A pair of water bugs feast on the carcass of a grasshopper in a small creek in the Bridger Mountains north of Bozeman. My research tells me water bugs feed on land-based insects that happen to fall into the water.
I had no idea these little bugs were flesh eaters. The grasshopper, by the way, eats leaves. I guess it’s kind of like huge bison, who eat plants, being devoured by smaller wolves.

What a cool photo! That’s quite a snack for those water bugs (“wolves of the water”)…
Thanks, Megan!
