Hi, I bought (about a month ago) a Myrmica rubra colony in a glass setup, a feeding area (quite large) tubed to a nesting area. The nesting area has been completely covered and dark, and damp, since they were put in the setup a month ago, but only a few stray foragers have gone in there, they refuse to move, and are gradually dying off. Recently i discovered all their brood are gone..
They always have fresh meat, from salami to moths and bugs, always fresh water, i take the bodies out, but they refuse to stop dying. Down to about 20 - 25 individuals now, any help would be great..
thanks.
