🚨 ARTHROPOD OF THE DAY 🚨
The family Phylliidae (often misspelled Phyllidae) contains the extant true leaf insects or walking leaves, which include some of the most remarkably camouflaged leaf mimics (mimesis) in the entire animal kingdom. They occur from South Asia through Southeast Asia to Australia.
Leaf mimicry often is elaborate among the leaf insects, with the insects’ wings and legs closely imitating leaf colour and form. Female elytra typically resemble, in their vein pattern, the midrib and veins in a leaf. Some species are even adorned with markings that resemble spots of disease or damage, including holes. Nymphs may sway side to side, as though mimicking the movement of a leaf in the wind. Leaf mimicry is thought to play an important role in defense against predators. Some species possess rows of tubercles on their antennae that when rubbed together produce sounds that may also serve to ward off predators.
