The Incredible Hummingbird Evolutions

The Hummingbird Hawk-moths are common visitors to a Norman garden when it is warm, sunny and dry. They love to hover around buddleja butterfly-bushes (summer lilacs), feeding without actually landing on the flowers.

The Hummingbird moth's hovering behavior, accompanied by an audible humming noise, makes it look remarkably like a hummingbird while feeding on flowers.

They are an evolutionist's delight, a living proof that similar natural tasks result in similar developmental solutions in species as far removed from each other as birds and insects.

It is just over 150 years ago that Darwin published 'On the Origin of Species' in 1859, but debate about the meaning of his findings still goes on.
