I have a 4 queen Myrmica rubra colony and think their behavior is a little „weird“.
Because they don’t have eggs or pupae (the last ants eclosed mid September i guess?) but tons of larvae. The concerning point is: the larvae don’t seem to grow anymore but the ants are still taking protein (a lot) and there’s always 20-30 workers roaming around in the arena. No matter what or how much food I give them they take it all (flies, crickets, protein powder, sugar, everything!). What should I do?
I keep them at high humidity and 20-23°C.
