What can I do to help this green lacewing?

I have found this buddy exploring one of my white walls and I trapped it under a bell jar. Where I'm living now, in Romania, it is winter, albeit a rather warmy one, but still with daytime temperatures not exceeding 10°C and freezing during the night. I know that these neuropteres hibernate during the cold season, but this one is fully awake. Should I set it free outside? Will it die because of the cold? What should I do with it?
