Hello ;)

Only one pic of this on 24th June 2009, it was on a waterlily leaf in my pond near Lincoln UK. Closest I could find is Macquartia tenebricosa.

WEll, it is something completely different.

There are 300 plus species of Tachinidae in the UK, it is not that easy to ID them from one picture !~

Thanks Theo, it was worth a try though.;)

Well, all calyptrates have them in varying sizes but in males they are usually bigger - big pulvilli are 'a man-thing' in the fly world :)

Could it be the same E. succincta as in the other thread by blowave?

Good thinking Jaakko! It was only just over a month from E. succincta, with some wing wear in that time. The back view of the other isn't so clear but put side by side they do look much alike.;)

I doubt it. The apical scutellar bristles are erect, the eyes seem bare and the vertex is very broad.
This suggests Lydella.
But since the picture is not convincing, I'm not gonna make this suggestion.

Thanks for the suggestion Theo, I can call it Lydella sp. for my own records but we have two Lydella speicies and to me Lydella stabulans looks good.;) Lydella grisescens is the other.

Well, it certainly isn't L.grisescens (grisescens is quite grey-dusted) ... but I share Theo's overall doubts about Lydella as a whole (it might be correct but something doesn't look right to me) so I would say 'indet. male tachinid'. It is a salutary lesson that not everything can be named to any degree of certainty and we shouldn't try to 'force' a name onto everything :)
