Giant Australian Spiny Stick Insect
Camouflage is the name of the game for these giant bugs. In their natural habitat, the Australian stick bug is almost impossible to see because it looks exactly like leaves on a tree. They are actually popular as pets, and suggested for young children as the leaf varieties are a bit more sturdy than a regular stick insect.
Their only real defense is their spiny legs and a smelly spray - that to humans doesn't really smell that bad. For once, this is a case where the real thing looks much scarier than it actually is. But still, if you were looking at a pretty group of leaves, and one of them got up and started walking away - admit it, you'd scream too.
So what's worse to you - something that just infests your house and is hard to get rid of, like bed bugs? Or would you rather encounter something gigantic, flying and stinging? That's a tough call - but we vote for neither!
