The workers are morphologically similar to L. alienus, but queens & males are clearly different & are much smaller.  The species is polygynous, without apparent colony barriers.  There are probably no nuptial flights, & intra-nidal mating has been observed.  In this respect L. neglectus has several features in common with the polygynous Japanese species L. sakagamii.  Workers forage in huge masses on aphids in trees.  It is argued that the rather late discovery of L. neglectus might be due to its artificial introduction in Budapest from a yet unknown area.]1 aLoon, A J1 aBoomsma, J J1 aAndrásfalvy, A  uhttps://antkey.myspecies.info/zh-hans/content/new-polygynous-ilasius-ispecies-hymenoptera-formicidae-central-europe-i-description-and
