Noooo! I had a pet Emperor Scorpion (what you ate) back when I was in high school many moons ago. She was an awesome "friendly" pet, until I put too many crickets in the tank to feed her, they ended up eating her... What's the dictionary definition of that?
Oh no! I took care of this friend's scorpions while he traveled, including emperors. I'm glad I didn't pour in too many crickets! I googled "crickets eating scorpion" and found a YouTube video. You're not alone in your trauma. I don't know about a dictionary definition, but the headline that came to mind is, "When the prey becomes the predator."
I like the headline haha! Crickets are mean in numbers...
