Last season I filled a box with Sempervivum and Sedum album which are blooming this year. The Sedum attract relatively many insects among which some wasps. I observed an Ancistrocerus feed and also this Carrot wasp Gasteruption erythrostomum ^[1]. The species is very active on the bee hotels in the garden but I hadn’t seen them feed yet so that makes this a nice observation. On two different occasions during the day a female drank on the flowers.
