Butterflies - block of stamps mint never hinged, Guinea-Bissau

After the K & auml; ferns, the butterflies form the second richest order of insects with 180,000 species. Every year researchers discover around 700 new species. The name butterfly comes from the Slavonic word Schmettern (sour cream, cream), to which some species are attracted. Butterflies are easy to spot. They have a small thin body with large wings. Many species have variegated wings. The head of the butterflies is small. Their habitat extends over the whole earth. Only in very cold areas there are no butterflies. The caterpillars can live for several years. Most butterflies usually do not grow older than two weeks. Some species also live so short that they don't even need to eat.
