On the Ings near Fulford. A long stretch of the river Ouse through York is claimed to be the only location in Britain where the colourful Tansy beetle (Chrysolina graminis
) is established. With fused elytra, they are unable to fly but will walk many metres. They have a conventional life cycle of overwintering in the soil, egg laying in spring, pupation during July with the adults emerging and feeding from July onwards. see Tansy beetle | Bug Directory | Buglife
Correction, Buglife in August 2014 reported another population being discovered at Woodwalton Fen, Cambs.
