Ok, I'll give everything a rundown of what I think.
Wasps/bees - Those bright orange/yellow marks are there for a reason, the black stripes give it more contrast. Most animals avoid them by instinct since those colors mean "I can bite back!" Of course some animals will take advantage or just...
I've seen mine eat wasps, but I've also seen wasps/bees land in front of them and they just glance and walk away. One thing I wish they would eat now is the love bugs/march flies. Those things are everywhere and they get all up in your shirt, blech. They're poisonus anyways...
