Happy Hylaeus

Spent a pleasant half hour or so in a lovely garden this afternoon,  in company with more solitary bees than we have so far seen in one place.  The combination of toasty sunshine and a large-flowered potentilla was very popular with some Hylaeus

 A bit of dancing about led to some bee-on-bee action - no wonder he has a smile on his face!
