hello I am new here so hi to all of you.

at beginning of July i found this one queen and I can't identify it, I am hoping some of you could help mi. This queen was found in Zagreb, Croatia (Central/Southeast Europe). Queen is cca 10mm in length and completely dark black, her workers are at moment small and brownish, bigger ones are black.

also it seams that queen likes very moist space, and workers are trying to find way out of test tube if they dont have food in test tube, as far I could observe they like worms and then they don't try to escape instead of that they help queen about larva
