The Ghost mantis (Phyllocrania paradoxa)
The Ghost mantis is a small mantis from Africa. It has evolved a remarkable camouflage which mimics a dried-up leaf to ambush prey, as well as allows it to hide from birds and other predators. Its colors change with each molt. Females can live upwards of eight months.
Ghost mantises primarily eat flies; but if food is short, they will turn to each other.
Leaf or Mantis? You decide!!!
