looks like crematogaster scutellaris
I second Crematogaster scutellaris, I also checked on ant maps and it says that they live in the area of the Mediterranean
one should still err on the side of caution because this could also be schmidti
Sorry, I am not good with the species in Europe, so I will just say that it is in the scutellaris group
Currently keeping:
1x Formica subsericea, 35-40 workers + maybe eggs
1x Crematogaster cerasi, only queen now, workers ded
*internal screaming*
1x Myrmica ruba sp around 10 workers + pupa
*New* 1x founding Camponotus pennsylvanicus + eggs that die (probably infertile)
*New* 2x Camponotus nova, one is infertile
*As you watch your ants march, remember that every thing begins with a small step and continued by diligence and shared dreams*
