The blog Urban Pollinators at http://urbanpollinators.blogspot.co.uk/ is written by researchers at a couple of universities and the entry today has some lovely photos of various bees and might help those of you who take pics of your bees and want to know what sort they are.
Great web site – will have a good look later. There is also a great little spread sheet produced by the FSC (field Studies council) with scale and enlarged pictures. In between A4 and A5 size with wipe clean covering. They also do one for ladybirds. They’re a good investment too.
