Length 5mm, walking under the grass in search of something. A tachinid? Early July in a garden in Vienna

not a Tachinid and i think that the only green Tachinid in our region is Gymnochaeta, which cannot be mistaken. Nay, should not be mistaken but i actually saw a blog with a Lucilia label for G. viridis. I guess it is possible to mistake it for something else.
Anyway, this female belongs to Calliphoridae. Bellardia vulgaris or viarum.
I do not have these specimens, so i cannot suggest a species.
I understand, according to Dr. Rognes, that viarum is more hairy than vulgaris. I'd have to see them myself to judge this feature. Otherwise, genitalia will be better.
the two thin black stripes on the mesonotum are useful for separating Bellardia from Calliphora, which can also be greenish.

In my camera roll I found photos of another specimen from the same place. I would say that there are no prominent discal bristles on tergite 4, which would favor
B. vulgaris, right?

I agree with your observation regarding the discal bristles. I have no experience with Bellardia so i do not feel comfortable naming a species. Bellardia cf vulgaris is better.
you could try to dissect the ovipositor for a positive id or you could send it to me. Otherwise, i leave it at confer.
