Remarks:

Of Lasius brunneus we found only a few specimens of which 3 males that were collected by hazard after or during nuptial flights. On 3 different green roofs, 1 worker was found each time. Gynes of L. brunneus found nests under bark, in bore holes of xylophagous insects or in crevices of branch breaks, typically in heights between 3 and 22 m above ground ( SEIFERT, 2018). Later workers start with active mining of the wood and emigrate to lower parts of the tree stem. Sometimes nests can also be found indoors in wooden constructions of buildings (DEKONINCK et al., 2021). We assume that the workers found here are not belonging to a nest on the green roofs but probably are foraging from nest in the neighborhood. Hence we do not consider this species as a part of the ant community on green roofs.
