Cucumber Green

Cucumber green spider, Araniella cucurbitina, in the axil of a new oak leaf on West Wickham Common, 30 April 2011.
You can judge its size by my fingers just behind it.

This is probably the best macro photograph I have taken with my Ixus 100. It shows very well the alien appearance of one of the small creatures I have been photographing recently; alien to us, yet actually more of the earth than we are.
