I just found this website:
http://www.buzzaboutbees.net/ and I'm delighted with it. There is loads of information about every type of bee, also wasps, presented in an easy and informative way
. It seems to cover just about any bee question you could think of, great and small.
I didn't put the link in the bees section because it's not about keeping honey bees, but about bees as wildlife. Also I have absolutely no personal link to the website, so I'm not supporting it for gain, just pure information (just in case you thought I did). Have a browse.
