Hello!
Today I checked on my founding Stigmatomma pallipes colony and found a worker locked on to the queen's leg. I managed to remove the worker with some difficulty. The two workers in the tube were not the queen's natural workers, instead, they were wild-caught helpers. I ended up removing them because of that sudden aggression. I still have them with me.
Should I put them back or not? They have been together with the queen for a month or two.
