Volunteers sought for Pollinator monitoring

Can you help monitor pollinating insects?

BWARS is supporting the new national Pollinator Monitoring Scheme (PoMS). The scheme is being launched this year as part of the Pollinator Monitoring and Research Partnership, which aims to combine improved analyses of long-term records with new systematic survey activity to establish how insect pollinator populations are changing across Great Britain.

How many eggs do Leaf-cutters provision?

I am masters student who is carrying out a study on how effective Bee Banks and Artifical Bee Boxes are for the conservation of solitary bees in Sandwell Valley. So far I have put up 7 Bee boxes around an RSPB site , all of which have been colonised by leaf cutters.  I have seen Megachile Willughbiella , Megachile Versicolor and possibly Megachile Centucularis provisioning leaf cuttings into different holes. Overall , I have seen atleast 54 holes with clear evidence of occupation across all 7 boxes, does anyone know how many eggs/ grubs one leaf cutter provisions in one hole?

A ball of Osmia bicornis

Has anyone seen this before?

A friend sent me some pictures after checking her bee hotel of a ball of Osmia bicornis that appeared to be resting together and waiting out the cold weather. It was a sunny day so my friend removed the tray and put it in the sun and pretty soon the bees warmed up and flew off. However she noticed that as soon as she put the bee box back together the bees returned to the same spot and resumed their ball like behaviour.

Is this commonly recorded in O bicornis when the weather isnt 100% favourable?

 

Many thanks

Look out for a new bee-fly

In April 2017 Rob Mills photographed a distinctive insect in his garden. This turned out to be the bee-fly Anthrax anthrax, a species never confirmed from Britain before. The bee-fly was sitting on a bee hotel in his garden near Cambridge, on a log drilled with holes containing solitary bee brood cells.
