Beautiful Butterfly Desktop WallpapersButterflies don't have mouths that allow them to bite or chew. Butterflies taste with their feet.
There are between 15,000 and 20,000 species of butterflies worldwide.
Butterflies breath through openings in their abdomen called "spiracles".
The largest butterfly in the world is believed to be S.E. Asia's Queen Alexandra's Birdwing female (Ornithoptera alexandrae) (up to 29 cm).
Butterflies can lay many hundreds of eggs, either one at a time, or in clusters.
Since butterflies are cold blooded it is necessary for them to warm up their flight muscles. This is done by basking in the sun in order to absorb heat.
