Where it's from: Southeast Asia
What to know: Leaves, meet your doppelgängers. These tropical bugs look so much like plants that it’s even tough for us to spot them. The slow-moving herbivores can be green, yellow, orange, or red, and they’re likely unchanged from millions of years ago, per researchers at Virginia Tech.
