Geograph - photograph every grid square

As part of its celebration of the International Year of Biodiversity, the Royal Botanical Gardens have a display "Butterflies, bugs and beasties" in the Princess of Wales Conservatory. It is to show how pollination works, and includes butterflies flying free in the glasshouse. This owl butterfly - genus Caligo, probably Caligo memnon - was in the tropical ferns section. They originate in rain forest from Mexico down to the Amazon basin. One of the eye markings is seen in the photo - they get their name because when their wings are open the two eye markings look like the eyes of an owl. They feed on rotten fruit - in the conservatory some were on fruit, some like this on leaves. They never fly more than a few metres.
