Video of extremely active ivy bee nest site with foraging and nest holes visible

Have you been lucky enough to see this new species of solitary bee which resembles a honeybee? They can be rather noisy! Have look at the video. The last bee to emerge in Britain during Sept and active till November just when the ivy flowers.

New videos added to species accounts

The Bee Species of Britain

Master beekeeper Meg Seymour, travels widely as seasonal bee inspector for FERA (Food & Environment Research Agency.) She is in charge of the bee project at Mendip Hospital Cemetery. Her talk “The Bee Species of Britain” will talk about the various types of bee, the contribution they make to the environment, the problems that face them, and how they can be helped.

Very active bee/wasp nest - 16 November 2014

I have an extremely active nest of wasps/bees in my garden, which seems unusual for this time of year. I would appreciate any help in what the possible species might be - whilst I have a keen interest in wildlife, I am completely new to the field of bees and wasps etc, so if anyone can point me in the right direction that would be great.

Impact of Honey Bees on other wild pollinators - particularly bees

I work on a Plan Bee project for Lancashire Wildlife Trust and have been asked by a local group if placing up to twenty bee hives on a Nature Reserve (that includes small areas of semi natural and created, fairly species rich grassland) will have a detrimental effect on other pollinators.

The location is Chorley, in central Lancashire.

I've wondered about this myself on a number of occasions though have not been able to unearth any scientific study or even anecdotal reports.

Megachile willughbiella confirmation please.

Hi all,

I caught a Megachile whilst surveying sand dune habitat on the Solway Firth in late August. I've just got round to IDing it and I'm 99% sure its M. willughbiella. However as it was in a coastal grassland site I thought it would be worth double checking just in case its actually a M. maritima. I know one of the distinguishing features is the length of the hairs on the fore basitarsus so I've taken a picture for comments.

Many thanks in advance.

Hypnorum "Bubble ?"

Can anyone help me please,
I found a hypnorum with what appeared to be a transparent oval balloon attached to the vent, and with what looked like an egg, and an oversized nematode stuck to the side.
I still have the photos.
It was still alive, but died several hours later.
Its something I have not seen before, and Im curious.

Many thanks


Andrena carantonica

I collected a female Andrena carantonica in West Sussex at the beginning of October and would be interested to know how common/frequent this phenomenon is.
