The Geograph project started in 2005 with the aim of publishing, organising and preserving representative images for every square kilometre of Great Britain, Ireland and the Isle of Man.
There are currently over 7.5m images from over 14,400 individuals and you can help contribute to the project by visiting https://www.geograph.org.uk

A feature of flowers of the compositae (Daisies, Dandelions etc) is the way that flowers structure themselves to fit Fibonacci numbers. (The Fibonacci series is 0,1,1,2,3,5,8,13,21,34,55 etc., where each succeeding number is the sum of the previous pair.) In this instance the anticlockwise and clockwise spirals in the yellow centre always add up to an adjacent pair from the series, in this case 13 and 21. (Not all individual flowers show quite as regular a pattern as this one.) Compare with http://www.geograph.org.uk/photo/6478556. There are also 21 of the white ray florets. One of a series of pictures depicting wild flowers in Carlton Cemetery. The management of the as yet undeveloped section of the cemetery allows a number of traditional meadow flowers to flourish. A slideshow of these flowers can be seen here http://www.geograph.org.uk/search.php?i=114777222 The beetle is a false blister beetle, family: Oedemeridae. Probably Oedemera lurida. My thanks to fellow Geograph member Richard Sutcliffe for identifying the species for me.
