These ants are actually much longer lived than expected. The nanitic batch has been dying off the past few days and the last of the nanitics and brood boost workers died today. That means they lived to be just under 9 months old, which is much more than the said 1-2 months.
Honestly I don’t know where people came up with this 1-2 month life expectancy for worker ants. It actually makes no sense at all, but seems to be believed by the majority of ant keepers. If ants only lived 2 months than how could they survive a 5 month hibernation? Not to mention that may not even be sustainable if a worker takes 1-3 months from egg to worker that would mean it takes longer for them to be born than they live for.
Anyway my Lasius neoniger workers that I have in my parasitic claviger set ups are now 13 months old. I noticed a couple have died recently, but the vast majority are still alive and they are about to go into a 5 month hibernation. I guarantee they are not all going to die during hibernation so I would put their life expectancy at minimum 18 months. You’ve got tetramorium workers at 9 months old, I’m fascinated to see if anyone else has been able to get an accurate life Expectancy for other species.
