Hi,

This looks similar to Delia platura but the hind femur has too many ventral bristles I think.

Taken on 11th June in my garden, near Lincoln UK.

You are right that it's not D. platura, but I can't see clearly enough to use the key with any confidence. I don't think I'd rule out Botanophila.

Thanks Stephen, I can crop closer on some parts of the top view if you need to see that, or lighten any parts. I thought the long hairs under the abdomen might be a clue?

The mouth protrudes a lot too..

Perhaps when Michael comes round ... The hairy sternites probably would be a clue to someone who knew what they were doing :D

Now that we've established we,re in wild guess territory, how about Paregle audacula?

From looking at the one photo in the gallery it very well could be, but it's not close enough to see the details well. How does it key out?

Maybe I should PM Michael with a link to this thread in case it gets lost.

Have you got Michael's key? http://tachinidae.../antho.php
If you work backwards from couplet 36 in the genera key you will see what it would need to have ;) It would also need extra hairs in the notopleural depression and a median av seta on t2, neither of which are clear in the photos.

Thanks for the link Stephen, I didn't know it was available there! I've downloaded it and sent an email asking for a password. I also sent a PM to Michael here.

I'll see if I can look at the areas you mentioned. :)

I've cropped off the part which might show the extra small hairs in the notopleural depression, what say ye? This is the photo I cropped the mid and hind legs from but didn't post the rest of it. I have lightened and sharpened it to help.

I don't know if this shows an av seta on T2, the lower of the two marked might be it? The other looks to be anterior.

Looks possible on both counts. Yes, the higher of the two setae you have marked is anterodorsal.

Thanks Stephen, I think you hit the nail on the head. B)
