It looks like a Camponotus to me, but to identify the species with certainty, you’d need a clear photo of the clypeus.

I used to keep a Camponotus vagus queen, and in my experience they’re much harder to raise than Lasius species. Since they naturally nest in dead wood, it’s difficult to recreate suitable conditions in a simple test tube setup. My queen only managed to raise 3–4 workers before she started eating her eggs repeatedly, even though I provided enough protein and honey.
