A pollinator to watch out for in your gardens: the Red-girdled Mining Bee – UPDATED

Last week, during one of my lockdown garden pollinator surveys, I spotted a bee visiting Germander Speedwell (Veronica chamaedrys) in the garden that I didn’t recognise. It initially confused me as it looked superficially like a Blood Bee in the genus Sphecodes. However the bee was clearly collecting pollen, which Sphecodes spp., being cleptoparasites, don’t do. A quick check in Steven Falk’s Field Guide to the Bees of Great Britain and Ireland and a look at Steven’s Flickr site, suggested that it was almost certainly the Red-girdled Mining Bee (Andrena labiata), which is frequently associated with Germander Speedwell.

I posted this video on Twitter and Steven kindly confirmed my identification:

The Red-girdled Mining Bee is considered “Nationally Scarce” and it has a scattered and southerly distribution, as you can see from the map above, which is from the National Biodiversity Network Atlas account for the species. It’s only recorded from about half a dozen sites in Northamptonshire according to Ryan Clark, the County Bee Recorder. However Steven tells me that it’s being seen more and more frequently in gardens, and indeed just the other day Sarah Arnold, who is also carrying out surveys, emailed me to say that she had spotted it in her garden in Kent.

So this is a bee that’s definitely one to look out for, especially if you have Germander Speedwell growing.

UPDATE: I should of course have also given a link to the BWARS account for this species, and mentioned that confirmed or suspected observations can be uploaded to iRecord.
