Hoverfly on Jerusalem Artichoke Flower.

Seem to have gone mad on bugs at the moment.  The allotment site has so many of these artichoke flowers - some of them may be cardoons - not sure what is the definitive difference except cardoons are smaller and rangier in growing habit.  I don't think many people eat them and not once they have flowered.  Today's light conditions were perfect to photograph them as long as you wait for a light cloud to cross the sun.  Their colour is so intense that camera sensors don't seem to like it - bit like bright reds and vivid pinks. 
A couple of extras for Flower Friday - that was the colour of the sky behind the hollyhock which heralded a very short shower - time to go home.
