Both my herculaneus and ligniperda have not taken any food or emerged since springtime.
I know they are still alive as I can see into the herculaneus nest and the ligniperda are still in their tube. Both still have broods and the queens are alive. But the colonies are not growing and there are no caccoons.
When they came out of hibernation they would take insects honey, and mealworms, but now I place food in the tanks and it goes completely untouched. I have also not seen them above ground or out of the tube. This follows a strange incident where my some of my ligniperda workers went crazy and started fighting eachother. Both tanks have some small bugs living inside them, they are not living on the ants themselves so do not seem like parasites. I've tried varying the temperature and humidity but nothing I do seems to make any difference.
