No interactions present.
Don't think it is a six spot burnet as it only has give spots on each wing (although I think there is a five spotted form of six spot burnet in some parts of Europe so I could be wrong).
If this were in Britain I would suggest one of the five spot burnets, but overseas I'm not confident to do that.
Yes...I'd be interested to know why an expert has agreed with 6-spot. Is it a peculiarity of this Iberian population, or is it just a miscounting of spots?!

According the Moths of Europe Volume 3 (P. Leraut) there are several subspecies of six spot burnet in Spain.
The subspecies gemella is from "the Spanish side of the Pyrenees" which is perhaps the closest location to that shown for this species. It is described as "medium width, forewing green or blue sheen, 5 quite small spots distinct, hindwing black border quite large." Comparing the pictures in Leraut I would say the spots on the specimen here are too large to be that subspecies.
The subspecies germina from central Spain (which I suppose might be where this location is) also has fives spots, a dark forewing with indigo tints and a broad dark border to the hindwing. The spots illustrated for this subspecies are larger and not to my eye inconsistent with this specimen.
Another Spanish subspecies is pyrenes has five spots but would I think be a bit east of this location (occurring east of the Pyrenees), although again I would say the specimens illustrated have smaller spots than the ones here.
All considered I would not personally be comfortable going beyond genus for this example, but would be very happy to learn from anyone more expert that it can be done to species (or sub-species) level.
Thanks, David, that is very thorough.
It will be interesting if Ron Elliott comes back to explain his agreement with filipendulae.
