I'm only guessing here, and I don't want to be responsible for cooking your ants, but I suspect that ligniperda actually need considerably higher temps to actually get going properly. PLEASE READ CAREFULLY AND TALK TO OTHERS BEFORE DOING ANYTHING RASH.
They are central European ants, and I would guess that the air temp in their natural habitat probably doesn't often exceed 30C. At the same time, they do nest in specific areas (Sunny slopes) and they tend to live in wood (which in the sun will heat up more than the earth). I am wondering if the ground temp and also the nest temp in full sun, throughout summer isn't quite a bit warmer than the air temp.
I acquired a small colony from someone on these boards in Summer. It came with a small heat map which I used under the ytong which I felt would warm the block to over 20C. The result was hibernation. It was only when I put the mat on top of the glass - so that it was heating the nest area directly that they became active (took a couple of days) and started feeding properly. Having kept ants before and considering the average temperature in their original habitat, I would've thought that the heat mat would make the nest too hot, and was surprised that they actively relocated to the hottest area and now seem to be thriving. I don't actually have a thermometer in there so can't tell you the temp, only that it is far hotter than I would've thought healthy for them. They now eat defrosted crickets, whereas before, in hibernation mode, they wouldn't touch them.
I might have this all wrong, and I really don't want to be responsible for cooking your ants, so I'd be interested in input from other people who've kept ligniperda, successfully and unsuccessfully. People talk about ligniperda growing slowly, and perhaps this is part of the problem.
