I’ve seen lots of predator bugs. African ghost mantises, chineese mantises, tiger beetles (which run so fast their eyes stop working temporarily), rove beetles and ladybugs, stink bugs and parasitoid wasps, and robber flies. There are so many amazing insect predators. You should see if your local library has an insect identification book you can flip through.
I’ve also seen some snakes and mammal predators like lions, tigers and bears (oh my!) at the zoo.
Humans are predators too!
