I find Wikipedia a great data base giving information which no other encyclopedia would give.
I do my bit when somebody tries to mutilate (not edit) an article by, for instance, deleting whole paragraphs or links just because he/she does not like it.
The gatekeeper (Pyronia tithonus) is a species of butterfly in the family Nymphalidae. Found across Europe, it is typically orange with two large brown spots on its wings and a brown pattern on the edge of its wings, although a large number of aberrant forms are known. The eyespots on the fore wings most likely reduce bird attacks; the gatekeeper is therefore often seen resting with its wings open. Colonies vary in size depending on the available habitat, and can range from a few dozen to several thousand butterflies. This male gatekeeper was photographed in Bernwood Forest in Buckinghamshire, England. The photograph was focus-stacked from 15 separate images.Photograph credit: Charles J. Sharp
