Bombus hypnorum mapping

The Bees, Wasps and Ants Recording Society (BWARS) have a mapping project for this bumblebee, so perhaps you could add this record to their site (http://www.bwars.com/index.php?q=content/bombus-hypnorum-mapping-project). The bee has only recently been recorded in the UK (2001) so it's interesting to see how it's spreading.

It seems to be doing rather well and it's range seems to be expanding with every year.

One theory is that bird-lovers might be helping it spread because of putting up nest boxes, which the Tree Bumblebee often likes to nest in itself! Purely speculative I might add...

Interesting to see how some other bees and wasps are doing the same - take the Ivy Bee, Colletes hederae, and the Bee Wolf, Philanthus triangulum, for example. I'm just waiting for the Violet Carpenter Bee to establish itself; I would love to see that beastie!

bee on primrose

Was the primrose growing in a garden or in the "wild" - I have spent a long time watching primroses and they are rarely visited by pollinators - if you see it pollinating them its worth photographing!

bee on primrose

The primrose is on a grassy bank,adjacent to woodland, in a town park.The grassy bank is part of one 'long' grass area of several through the park being managed for wildlife, with the grass being scythed in the autumn. The primroses were planted 1 year earlier along with other wildflower species. The petals are damaged due to sledging in the recent snow, but the plant survived! A hazard of managing for wildlife in a public area.
