Remarks:

Of this Hypoponera species we only found alate gynes and no workers. This suggests that it probably did not settle on the green roofs we sampled, however attempts might be successful in the future. This cosmopolitical species is known from greenhouses in north Europe and sometimes also settles outdoors in compost heaps, accumulated litter of mowing activities etc. Also in Belgium and the Netherlands this species has been found already several times in litter and compost heaps (DEKONINCK et al.; 2012; BOER et al., 2014). Maybe green roofs in Flanders might be a potential place for this species to settle in the future, if enough litter is accumulated on the roofs.
