Roger,
It's a good job I thought to check it on the map! Another first I have for Lincolnshire then as well as a few rarities...

I must check all my other Syrphids too now. I'll get my grid details sorted then send it to you. Your searching here did not end in vain
Chris, I have some more Tachinids I need to ID too so should get onto that soon, the weather needs to change for the worse to give me more time.
