This time I think I know at least the family. Would it be a Tachinidae?
Thanks in advance, Sarah

See Sarah, it is not that difficult after all.
Tachinidae it is and when you get a non-typical (= non-greyish) Tachinid, it is nine out of ten times a member of the subfamily Phasiinae, with hosts exclusively in Hemiptera - Heteroptera.
As in this case.
It is a member of the genus Cylindromyia.
Recognized by the special wing venation: long and upward curved petiole of topcell, by the general build, very elongated and by the absence of palpi (not visible in picture).
This might be C. interrupta, but there are many species, so species is difficult to tell.

Thanks so much Theo and I'm even more encouraged as I nearly put down Phasiinae as it seemed to have many features in common with a couple of others in the subfamily I've photographed. Thanks too for taking the time to explain the basis for your definition. It all helps me to learn ;) Sarah

I have had a very good look at the second picture and you can see, just, a glimpse of apical scutellar bristles (apart from the much larger lateral pair). This would make the species auriceps. A female, by the way.
