(Lepidoptera) This order includes about 174,250 species distributed into 126 families of insects ranging in size from very small to large with a cylindrical and smooth body. Their boy and wings are covered with colourful scales giving them a distinctive behavior in terms of taxonomy. Their head is relatively small and can move freely using a thin neck. They have big compound eyes with or without two simple eyes. While antennae are clavate in rhopalocera , they are pectinate, bipectinate, filiform or plumose in butterflies. Larvae of insects of the Lepidoptera order are usually cylindrical having three pairs of thoracic legs and usually five pairs of abdominal false legs. While most of the larvae feed on plants (leaves, fruits or dig tunnels in the stems and leaves), a few species are predators of other insects. Their metamorphosis type is complete (egg - larva – cocoon - complete insect).
