Hi, I have had a colony of Camponotus ligniperdus - queen and about 15 workers - for about 3 months now. The queen has been laying eggs for about 8 weeks but none of them seem to be developing.
I have a foraging tank and a formicarium with sand and loam and while they have dug tunnels in the sand, they prefer to live in the tube between the two.
Any advice?
