I have a big Myrmica rubra colony for a couple of months now.
There are 3 queens, a lot of workers and a lot of brood. I also have some flying ants since this week.
But the last 3 weeks or so they act really strange.
They kill each other sometimes when they are in the outside world,
Only there and not in the nest itself.
Does anybody have this same experience.
I've heard this specie act sometimes strange.
( Hope you guys understand my english )





(lol)





And they will be a bit smaller than with more queens.
