Keeping track of invading tree bee

03/06/2010 09:34:38 Commonly make their home in bird boxes

 
June 2010:
Worcestershire's wildlife enthusiasts are being asked to keep a look out for a new bee. The Bombus hypnorum, or tree bee, arrived in the UK in 2001 and has been steadily working its way north, reaching Northumberland last year.

NEW TO THE UK: The tree bee looks quite
distinctive

Worcestershire is on the western edge of its range, and now the county's Wildlife Trust and the Biological Records Centre want to gather information about where the bees are nesting.

Tree bees get their name from their natural nesting sites in hollows of trees. However, they are also commonly found in bird boxes in gardens.

Tracking its progress through Britain

Harry Green, trustee of Worcestershire Wildlife Trustt and committee member of the Worcestershire Recorders, explained: ‘It's really important that we gather as many records of this bee as possible - and not just for local interest. Any records we receive will feed into a national database that is tracking the arrival and spread of this bee in relation to climate change.

‘The bee is very distinctive with a ginger-brown thorax, black abdomen and white tail. It is so dissimilar to other species that there should be no misidentification.'

Readers are invited to send records to the Biological Records Centre. Photographs, even from a mobile phone, would be appreciated to confirm the sighting.

Tree bees are not generally aggressive and will not sting unless handled roughly or they feel that the nest is under attack. Male bees do not have stings, although worker bees do - nests should be observed quietly from a few metres away.

Tree Bees in my garden

I've had tree bees in one of my bird boxes in my garden in Hockley in Essex. They've been there for about 3 months but have now disappeared. Today I opened the nest box up and in amongst the remnants of an old bird nest are lots of small cells. I noticed some larve moving about so I've closed it up again and left them alone. Does anyone know how long it will be until the larve change into bees or will they die as there are no adult bees there anymore. Thanks.

Tree Bees in the eaves!! in Yorkshire.

I live in York and have recently had new fascias and soffits fitted on my house and have now got some tree bees nesting behind them. They use the mortar channels between the bricks to get in there!! There are often up to 20 of them buzzing around the guttering. They seem harmless but are incredibly noisey especially at night in their nest as they are just beside my bedroom window!!

Regasrding Tree bee invasions, I was at the Tolkein weekend here at Birmingham where a bumble expert was advising on encouraging them into the garden. I askeorumd zbout a bee than had recently decided to nest in the house eaves. According to him the description I gave fits with Bombus hypnorum and seeing this pictured on the website I think that is comfirmed. I hope that whoever is tracking the spread of this species may find this this of interest.

Bombus hypnorum, or tree bee

We spotted this bee for the first time in our garden in Sheffield this year. It is present in very large numbers and we have discovered that it is nesting under the flashing of our extension roof.

There are often several bees on the wing darting around outside the nest and, from the other comments posted on this site, it may well be that they are 'dancing'.

For the 2nd year in a row, I have seen bees with a rich brown thorax and black abdomen--not able to see if rear is white. They are constantly on my standard lavender bush, up to 6 at a time. I think they are workers, all smallish. I live in Fleetwood, Lancashire--we have our own weather system--the last 2 summers have been quite warm and sunny. Are they likely to be tree bees?

A Bee keeper confirmed that we have a Tree Bee nest in a bird box in our garden in Sheffield. There are sometimes up to 20 male "dancing" bees outside the nest and the workers queue to bring their pollen/nectar into the nest. He informed us that it was a very healthy nest stating that there could be up to 400 bees living there.
He explained why the smaller bees were hovering around and when I informed him that I had actually seen one of the smaller males mating with what I now believe to be one of the queens on a ledge under the nest he was surprised as he understood them to "do it" on the wing.
