Gmachówka ruchliwa Colobopsis truncata (Spinola, 1808) (Hymenoptera, Formicidae) w południowo-zachodniej Polsce ze szczególnym uwzględnieniem Wrocławia / Colobopsis truncata (Spinola, 1808) (Hymenoptera, Formicidae) in Southwestern Poland, with a particular focus on Wrocław.

Presented data supplement and expand the current knowledge on the distribution of Colobopsis truncata (Spinola, 1808) in Southwestern Poland. Research conducted in Wrocław demonstrated that C. truncata inhabits not only old oak trees (Quercus robur) but can also be found nesting on young native oaks (Quercus robur), in peeled or dead sections of invasive red oaks (Quercus rubra), as well as on trees belonging to the following species: Acer pseudoplatanus, Populus alba, Populus x canadensis, Alnus glutinosa, Betula pendula, Platanus acerifolia, and Ulmus spp. Some observations come from young forests, where ants most likely established their nests in hollow branches in the leaf litter. One observation indicated that holes bored in dead wood by other insects may be used by C. truncata as nesting sites.
