Wow, nice photography! I've never seen them before, but perhaps I just haven't been looking for them. I've heard they can be a real problem if they start eating your house. (This reminds me that I need to clean the rain gutters on my house - termites where I live like wet wood.)
You are a true friend. how do you think they can live in a snowy place?
I think it is a different kind of termite that lives around here. It is more cold hardy and my guess is that it can survive short freezing weather by finding shelter in certain areas that are more protected. I'm not really sure how they survive in really snowy weather - of course if it gets bad enough there are no trees for them to eat.
Here their food is wood. As in Europe I think termites are not a scary and threatening animal there. I think people in Europe no longer live in wooden houses and they live in concrete houses. Really like that?
