I believe this is my first record of this hoverfly. Eristalis inticaria female. (The furry hoverfly). According to Nature Spot, this large hoverfly is unlike the other UK Eristalis species in being a furry bumble bee mimic. (The males are dark with a reddish-brown tail) whilst the female (seen here) has a white tail and is somewhat larger. Nature Spot also says this species always has a yellow scutellum. Paul.
