17mm, Clitheroe UK, 8 August 2011. Can't give the exact size, but bumblebee size - [EDIT: size established at 17mm from photos taken on 9 August]. The plant is Golden Rod (Solidago canadense I think). This seems to be a female T. grossa; am I right, and should I be finding this in Lancashire?

I love these beasts. If dark calypter -> Tachina grossa. Most likely.  |

Thanks Jorge. I think part of the calypter shows next to the alula, and it looks dark. |

I found them at 1200 m in Rubus leaf always challenging me and almost "smiling" as it was like saying: "you don't catch me!"... and then all ends well.. with the fly in my net.

It has to be T.grossa here in the UK (and the calyptrae are clearly black) - we do not have T.magna  Nice photo

and fortunately for you... you don't have Tachinidae lovers as your neighbours... it is not good to feel their revenge without having the specimen. |

They're cropping up fairly frequently at the moment - I seem to get a few emails every week from people (often non-entomologists) who have seen them in their gardens or in the countryside

Chris, I feel sorry that you do not have Tachina magna in UK. If I found some, I promise, at least, one T. magna specimen for you. Stephen... Clitheroe is a small town and civil parish in the Borough of Ribble Valley... must be very easy to find you.

 I'd better alert the security forces! |

Now I have my reward for not killing this splendid beast. It has stayed for more than a week, and since it discovered the Sedum spectabile has been very easy to find. Today I found we have two females, and of course I have been looking out for a male. Then I saw this 10.5mm fly trying to mount a big female.

This is a male Eurithia.

Damn! I thought it wasn't getting far with the girl. Now I see from the Gallery that the male looks much more like the female. I'll keep looking

Yes, it looks like Eurithia anthophila.

Thanks Erikas and Stephane. At least I have a new species for my local list - and I'll get over the embarrassment eventually
