In my post ‘Backyard Safari‘ from September 15th I included this photograph of a magnificent hoverfly which I identified as Volucella inanis:
I subsequently received a comment from Roger Morris of the Hoverfly Recording Scheme (HRS) to let me know that I had incorrectly identified the fly and it is in fact Volucella zonaria. So thanks to Roger for putting me straight.
When it appeared in my garden I mistook it for a hornet, it’s our largest hoverfly and I’ve seen it described as a ‘hornet mimic’. The adults feed on flowers such as buddleia which may be why it appeared in my garden, and the larvae feed on the detritus which accumulates in the cavity at the bottom of wasp nests. It wasn’t recorded as resident in the UK until the 1940’s when it appeared around London and then spread across the south of England to the west country. It’s population is still most dense in the south east but it is regularly recorded in the east Midlands with occasional recordings in the northwest of the country.
