This forum is a place to discuss matters related to BWARS and general matters related to aculeates.
It is not intended as a forum for identification queries. We may add this feature in due course, but meanwhile, if you need help identifying bees, wasps and ants, please use either iSpot or the BWARS forum on Yahoo.
BWARS has not yet prepared a species account for this species. The notes here are copied from Steven Falk's Flickr page forH. scabiosae with distribution details from Guernsey Biological records Centre.
H. scabiosae has been recorded from the Channel Islands, but not from mainland Britain.
It was first recorded in Jersey in 1902 (Richards, 1979) and was first recorded in Guernsey in 1998, where it had a largely coastal distribution.
This Honey Bee-sized Halictus is easily distinguished by the ring-like bands on the tergites. These comprise an anterior and posterior buff band on tergites 2-4 of the females and just a whitish posterior band on segments 2-6 of the very elongate males. The male hind tibiae is almost entirely yellow without the dark marks of species like H. eurygnathus or H. quadricinctus.
Nesting aggregations are formed in light soils, especially the vertical faces of soft rock cliffs.
Hibernated females appear in April, males and new females in July.
It can be eusocial in some instances (with smaller non-reproducing females acting as workers) or simply communal (with no apparent workers) in others.
It forages on assorted flowers but with a particular liking for Asteraceae (e.g. thistles, knapweeds, Catsear).
I live in Austria where we are currently approaching winter with temperatures around 5C currently. 2 days ago I found what I identified as a Blue Carpenter Bee, which I understand from my research is an endangered species in Europe. See attached photo.
I found it on our lawn hardly moving, but suspecting that it may only be cold not dying, I brought it inside to warm up. It is definitely alive but I think it was trying to find a hiberation spot.
How can I keep it alive and help it hibernate?
My internet research has not produced any help on this topic.

The NBN are running a short project seeking to classify recorder motivations, and understand what support different recorders prefer. They're using both questionnaires and interviews, and need as wide a range of responses as possible to cover the diversity of circumstances and perspectives. If you collect data from the environment and would like to be included, further details are here:
This year (working on the Plan Bee project for Lancs Wildlife Trust) I found - surprisingly - Andrena tarsata on a fairly isolated / degraded site containing a good number of Tormentil cushions (Potentilla erecta) in Skelmersdale.
Skelmersdale is a new town (1961) though has a relatively large resource of informal public open space / road infrastructure (mostly farm / forest remnants) though acid grassland - and Tormentil more so - is scarce in lowland Lancs as a whole.

A significant leap north west for Colletes hederae is apparent, with the discovery of a well established population around Llandudno in North Wales, on 8 October. A large nest aggregation was found on Little Orme as well as individuals at ivy and nesting in a roadside verge in nearby Llandudno. The latest map includes these new records. Latest Map
BWARS member Ian Cheeseborough and Pete Boardman at the site of the recently discovered nest aggregation of Colletes hederae on the Little Orme.
We recently received a message from a member of the public stating:
"For your info we came across a beautiful specimen of a paper wasp today in dalgety bay. We had old book which said they were not found in UK but obviously not anymore"
They do not have a photograph nor the specimen. Forgive my ignorance - I'm aware that at least the common wasp builds their nest out of a type of paper, but is the individual referring to a different, specific type of wasp?
