Solitary bee
Description:

A small solitary bee from last year that I never identified, feeding on a cotoneaster flower. Andrena sp. I think, but can anyone take it further with any confidence/correct this? Too many, too similar bees for me....

Many thanks for the steer on this Chris. I know many Andrena spp. are notoriously hard to be sure of from photos and there are only a couple - fulva and cineraria - I'm confident with at all, but I'd like to learn to ID more and knowing what to look for really helps!

Andrena

Hi Nick, I'm not certain on this one but I think it's A. barbilibris for the reasons stated. I find males are far more difficult than females but look out for the colour of the face, rear legs, scopae and more importantly the size. Unfortunately very few people put a size in mm on their postings.

HTH, a bit anyway

Andrena

Thanks again Chris. As for sizes, unless I post soon after taking a pic I sometimes forget how big thugs were as a photo can be deceiving! I do remember this one was small and delicate, though, and the Cotoneaster flower helps give scale. The bee was around 10mm I reckon.

Size

That would be about right for this species.

Possible

I'd say a possible as they are somewhat tricky to ID. Hopefully an expert will confirm or re-identify.

Andrena

Many thanks for the extra input. I did wonder if it was a female, but defer to others on Andrena species ID beyond the couple I can recognise.
