Gastrophilus intestinalis range in the UK?

[Suffolk-Chris]

Does anyone know what the Northern-most and Southern-most range for the horse bot fly (Gastrophilus intestinalis) is in the UK? I know they are a problem in the central area of the UK but many people I speak to in my work say that they never see them.

I'm currently running a small survey for sightings of the beasties on a year to year basis to see if they start to appear in new places with the odd seasons we seem to be having, so any sightings would also be gratefully received.

I have just checked the NBN Gateway for Gasterophilus intestinalis (check spelling)

Very few records, but amazingly, there are records from St. Kilda!! The southernmost is from Devon/Cornwall

Good hunting. You shoukld try the Dipterists Forum (if you haven't already)

Best, Stuart

Bot fly eggs appeared on my horse yesterday (25/8/2007) for the first time this year. He's grazing near Butser Hill, Clanfield, Hants. Until this year he's always been in West Sussex and never had bot fly eggs (apart from when I was at college in Cirencester).
Hope that helps.
