While searching for another source to verify this fact, I learnt from wikipedia that Formica polyctena ants are near threatened: https://en.wikipedia.org/wiki/Formica_polyctena Good that they got out of the bunker.

Given that ants make 20% of the entire animal biomass on land (https://www.youtube.com/watch?v=7_e0CA_nhaE), it didn't cross my mind that subspecies could go to extinction ^^
