1. Location of collection: southern part of Austria, both found in a forest
2. Date of collection: both colonies were caught 3 weeks ago
3. Habitat of collection: forest, both colonies were nesting in a cobnut
4. Length (from head to gaster): Colony 1: Worker: 2-3 mm, Queen: about 4 mm
Colony 2: Worker: about 2 mm, Queen: about 3 mm
I thought both of the colonies were Temnothorax nylanderi, but because I'm a newbie I wanted to ask you guys for confirmation or other ideas on the species of these two colonies.
I hope the quality of the pictures are ok. They are the best I can get from this tiny ants.
Thank you and if you need any more information feel free to ask!
