MM. I agree that the antennae are orangy - but this is a good hundred miles north of the northward boundary of C. soror so I suspect it is C, scutellata

It would be worth taking some specimens John - if this was soror it would be quite a major find.

Thanks for this one too - it illustrates the point about antennal colour - a really tricky issue.

Regards

Roger

It was the orange tipped scutellum that caught my eye having seen that mentioned in the facebook post as a feature of C. soror.
There is no mention of that in your book with regards C. scutellata.
I guess 100 miles is no distance at all considering tree bumble bees are up here in large numbers now having moved northwards from Kent in just a few years Wink

Hi John

Thanks for the alert - we need to address this - scutelata also has a yellow tip o the scutellum - or at least I should say some in both species!

Looking at the maps, I think the distances involved are such that this really would be an amaxing record. There are oldish records from the Grange over sSands area - a known area with a southern micro-climate, after which it struggles into the south Pennines and north Wales. Bearing in mind the problems with antennal colour discussed this weekend, I think I would like to examine specimens!

Do please grab specimens - lets see if we can crack this one.

Best wishes

Roger
