I've mentioned this is other threads but one of my two Camponotus pennslyvanicus colonies has a queen who has totally stopped laying for about 3 weeks now. I saw a few eggs about two weeks ago but then they vanished.
The colony has about 35 workers. They are in a small wooden nest. They have a big outworld with driftwood, sand, sugar feeder, water feeder and I give them crickets and fruit flies and wet cat food. They don't eat much. They almost never leave the nest. They don't have anything to do I suspect without brood to raise.
So, frankly it's very boring to watch them. I feel like they will just keep eating a little every 4th day, maybe drinking some water... all of the colony has very full gasters. They aren't hungry.
The queen looks healthy. She rests just like my other camponotus queens, she'll move around a little if you shine light on her, she has no outward signs of sickness.
They have one of the nicest outworlds of any of the colonies and I'm kinda annoyed and inclined to give them something smaller since they don't seem to want to use it.
Is there any chance of this queen coming back to laying again? Or do I just have a bunch of sad ants who will slowly die over the next 3 or 4 years? Have any of you had a queen who stopped laying in the summer start again?
My current hope is that if I put them through a nice cold bracing diapause in the fall ... maybe it will "reset" the queen. It's sad that I can't give her workers to the other queen as they would just fight. The workers include many lovely majors with big heads and long legs. I wish I could give them something to do.
What have you all done about your sterile colonies? Colonies that just kinda stalled out, but the queen is alive?
