bivoltine bees

Hi All,


Can anyone help. Was looking for any studies of nesting in double brooded andrena. Can't find much on google scholar. Does anyone know of any studies of relationship between spring and summer brood nesting. Ideally such as nests dug out containing both broods of one species. Have found plenty of studies of spring only or summer only nests.






Violet carpenter bees, Exeter

Hello, hope everyone has had a good field season

I've been forwarded photos, and just yesterday two specimens, of Violet carpenter bee, from allotments on the edge of Exeter. I'm assuming X violacea. Does anyone know of any other UK records this year?

The allotment holder reported the bee buzzing around her allotment throughout July. The two specimens found yesterday were picked up from her garden nearby. If the record is of general interest I can find out some more details.




Solitary bee filmed in slow-mo

Spotted preparing a nest in the frame of my BBQ ( and of course now off limits for cooking) 

the bee is carrying a bright green load .. welcome input as to what it is .. the appearance is of a pupa but the colour suggests leaf cuttings . Multiple visits observed . 

. Apologies but the video file cannot be uploaded so I hope the description works
