I have been looking at some bees online and found this link
Here David has a photo of a similar bee called early mining bee but it has much shorter hairs can you tell me if this is due to natural variation within the species or whether Davids photo is A. varians (a bee that is similar to early mining bee but with shorter hairs)
David's pic is of a female A. haemorrhoa and this one looks like it is a male. They are very sexually dimorphic.
I am not sure where the name "Early Mining-bee" comes from as there are plenty of Andrena species on the wing well before A. haemorrhoa. With a specific epithet of "haemorrhoa" you might expect a more colourful English name.
A. varians is a pretty rare species. Males would be quite impossible to id from pics, and females might just be do-able if the right bits are on view. What made you suspect A. varians? There are a lot of Andrena species to choose from (65-ish in the UK) and this seems an idiosyncratic choice ;-)
Thanks for the comments Stuart, as to why here's the link
Thanks for the link. It is pretty garbled and the pic looks very like an extremely cold female A. haemorrhoa to me. However, I can't see T1 (essential for id of A. varians) so I would reserve final judgement.
I do know one person who get A. varians in huis garden, but I have only ever seen the thing in 2 sites over the last 23 years
