What is walking leaf?

Walking leaf

Many extraordinary things exist in nature. Insects
and animals change their size and colour according
to their requirements. In  nature,camouflage means
a disguise used by animals or plants to conceal
themselves from their enemies.

         And one of the best camouflage to be seen
in the animal world is that used by an insect known
as walking leaf. This  insect spends its live in trees
and shrubs, feeding on leaves at night and resting
quietly during the day. Nature has given it a set of
green wings which are shaped  and ribbed exactly
like the leaves of the trees in which it lives.

This helps it in hiding away from its enemies.
