Plenty of Tansy Beetles seen next to the River Ouse in recent weeks. The riverbank south of the Naburn Swingbridge near Bishopthorpe is a good spot and several pairs were seen doing their best to keep the population going. This is a York speciality, with the tiny range of this jewel being along the Ouse either side of York. There have been some found in recent years at Woodwalton Fen, Cambridgeshire, but I suspect an introduction (along with the Purple Emperors that have turned up there!) as I can't believe this big shiny critter was overlooked previously as this well-monitored site.
