Many insects disguise themselves to bamboozle their foes． They pretend to be stones, seeds, blades of grass, and even dewdrops． The prize for the best disguise must go to the walking-leaf beetles of India and the Philippines．

　　The eggs of these insects look like seeds． When the young hatch, they are glossy-red copies of the buds sprouting on the bushes they inhabit． The adult beetles' green bodies are shaped and veined to look exactly like the leaves they feed on． Their flat legs resemble small leaves with ragged yellow-stained edges． When it is windy, walking-leaf beetles often hang by two legs and turn their bodies to and fro like breeze-blown leaves． At every stage in life, the walking-leaf beetles can hoodwink their enemies．
