My Camponotus queen has had cocoons for a long time. She hasn't opened any of them. Should I try to open them myself? More larvae have spun cocoons but the older ones never become nanitics.

Those are not ready to hatch. The queen will open them when they are ready

Yes, they are darker than that before they hatch.

18 days is pretty short for Camponotus pupae. Generally the pupal stage will take as long as the previous two stages combined. I'm sure your queen will eclose those pupae when they are ready.

I agree, cheetolord02

Camponotus pupae will get so dark you can see the ant inside.
