A rare moth has been found on the roof of the House of Commons.
The unexpected discovery came when a trap was put in place overnight by the charity Butterfly Conservation.
The Tree-lichen Beauty (right), a migrant from Europe, was until recently rarely seen in this country and in the 140 years up to the start of this century fewer than 50 examples were reported in England.
Mark Parsons, head of moth conservation with the charity, said: "This find was a real surprise. It seems that the Tree-lichen Beauty is now becoming resident in parts of the capital, possibly as the beneficiary of climate change."
Several examples of another migrant moth, the Silver Y, were also in the trap.
The trap was the idea of Madeleine Moon, Labour MP for Bridgend.
