I found this small tachinid basking on the leaves of a Prunus lusitanica. What can be said about it?

Couldn't it be a Rhinophorid?

It looks like
Microsoma exiguum, Tachinidae but it's a bit early for this species ?

It looks identical to the photo of
exiguum in the Gallery. :) Tschorsnig & Herting (1994) says "
End April to Mid October (without a peak) several generations." and the range of that key is central & northern Europe so perhaps in southern Europe it emerges earlier in warm years?

In any case,I agree with Microsoma exiguum.
The wing venation around the stalk is typical.

Thank you everyone:)! I can see that it's another parasitoid of weevils. In fact I'm seeing lots of weevils in the habitat of Rondania and Microsoma. Maybe I'll catch some to see if something gets out of it.

What would be the "jizz" of tachinids?

Tachinids are calyptrate flies (usually) with strong bristles and (usually) with a bent median vein ... but you also need to know what sarcophagids and rhinophorids look like to be able to eliminate them ;) Then there are the phasiine tachinids that are calyptrates that look quite like syrphids - ie. without or with few bristles.
