Philippine leaf insect

Phyllium philippinicum

Also calledWandelndes Blatt (German, leaf insects generally) · Phyllie (French) · Insecto hoja (Spanish)

A flattened, bright-green stick-insect relative that is almost indistinguishable from a leaf, complete with 'veins' and brown 'bite marks'. It even sways gently as if moved by a breeze.

Phyllium philippinicum is a species of leaf insect in the family Phylliidae. It is endemic to the Philippines. Wikipedia

§1

What it can do

  1. iBody and legs are flattened into leaf-like lobes with vein patterns
  2. iiRocks from side to side while walking, imitating a leaf in wind
  3. iiiFemales can reproduce without males (parthenogenesis)
  4. ivEggs look like plant seeds
§2

In the field

Field marks

  • aBroad, flat, leaf-shaped green body, sometimes with brown or yellow patches
  • bLeaf-like flaps on the legs
  • cFemale forewings marked with a pattern resembling a leaf's midrib and veins
  • dMales narrower, with long antennae and functional hindwings
Not to be confused with
Many Phyllium species are near-identical and are separated by egg shape, the leg lobes and range. In the wild its main 'lookalike' is a leaf.
Where to see it
Philippine forests; one of the most commonly kept leaf insects in captivity.

In the old herbals & bestiaries

No plate in the Source Library names this exact species, so these show its closest relatives as the old naturalists drew them: same genus, or the same kind of animal. Click a plate to read the page it came from, with translation.

Marginalia

Leaf insects astonished early European naturalists; Linnaeus named the first known species Gryllus siccifolius, the 'dry-leaf cricket', in 1758.

Curiosity

Newly hatched nymphs are reddish-brown and look like ants or dead leaf fragments; they turn green only after their first meals of leaves.
