What are Walking Leaves?

Aug. 30, 2023

An international research team recently described seven previously unknown species of leaf insects, also known as walking leaves.

About Walking Leaves:

  • Walking Leaves, also called leaf insects, are insects that look very similar to leaves. 
  • They are any of more than 50 species of flat, usually green insects (order Phasmida or Phasmatodea) that are known for their striking leaflike appearance.
  • They feed on plants and typically inhabit densely vegetated areas. 
  • Distribution: Their natural range extends from islands in the Indian Ocean, across parts of mainland South Asia and Southeast Asia, to Papua New Guinea and Australia in the western Pacific.
  • Features:
    • They measure roughly 28 to 100 mm (1.1 to 3.9 inches) in body length.
    • Males tend to be smaller than females. 
    • They are mostly brown or green, some slightly speckled or have serrated edges like nibbled leaves.
    • Movement: They sway and rock back and forth, imitating the motion of leaves in the breeze.
    • Female walking leaves cannot fly. Males can fly short distances thanks to their well-developed hind wings.
    • The arms and legs of walking leaves can regenerate.
    • Reproduction: These insects reproduce sexually, with females laying eggs. The eggs often resemble seeds or plant structures, adding to their camouflage.
