A Croatian study (Bujan et al. 2015) found L. platythorax was numerically dominant in a sampled fen and two adjacent suceesional habitats (reed and willow; young forest: a mixture of willows and different woody and herbaceous species characteristic of the surrounding beech forest). This ant was also present in an adjacent mature beech forest.
