Leaf bug (Phyllium giganteum)
The constant wobbling as they move is a part of their disguise, making it seem as though the “leaf” is only moving because of a light breeze.
If you blow on one it will also shake around in the hopes of matching any actual surrounding leaves
Did you know at the set of Capitan America 2. Chris Evans couldn’t tell apart Scarlett Johanson’s stunt doubles from her so he would start talking to them as in they were Scarlett and the stunt doubles played the game ” How long would it take Chris to figure out im not Scarlett” . Apparently the record was 10 minutes.
