There was a little bug flying and it got trapped!

You guessed it!  Venus Fly Trap

Venus Fly Traps are amazing critter-eating plants.  They actually help spiders on their duty patrol.  And help with air patrol.  Every plant helps with air patrol but we're just talking about the Venus Fly Trap for now.  The only way that a bug can get snapped by the Venus Fly Trap is if it touches the soft jaws.  If something touches the soft jaws, including humans, it could die.
