This article about bumblebees' decline makes interesting reading. Elsewhere, articles expand on the theme but any way it's pitched it's bad news for bumbles .
Still can't make the link work, but if you google "science mag: bumblebees" it goes straight to it.
It's the heat that's doing it but it's jolly cold today !!
^Found this beauty in my garden earlier . It looked a bit drowsy though, so I moved it and put it on a heather bush where I've seen other bumble bees feeding. Went to check on it a bit later but it was gone, so I assume its all good
Edit: I don't know why that image is not showing
Edit 2: got it working
Seen in my garden today, a bee I never recognized. Was black with two grey stripes up near its head. Looked it up and it was a Andrena cineraria - ashy mining-bee. I reckon it is the first time I have ever seen one.
