Scarce bee seen at Wet Meadow

I was on a one day bee course yesterday courtesy of the Wye Valley National Landscape, We spent the afternoon session at Trellech Wet Meadow just a couple of miles from The Beeches. There weren't many bees about but just as we were finishing a scarce bee was found - the Red-shanked Carder Bee (Bombus ruderarius). I'll have to keep my eyes out here - that would be a major addition to our bee list. The photo is from Wikipedia Creative Commons (Ivar Leidus, CC BY-SA 4.0 , via Wikimedia Commons)
