Three tightly correlated groups were identified, representing a putative aerial plankton guild （Chironomidae ＋ Ceratopogonidae） and two tree-trunk guilds, one of which （Dolichopodidae ＋ Germaraphis） is possibly connected to more open or/and more hygrophilous habitats than the other （Sciara zone Diptera ＋ ＂Acarus＂ rhombeus）. The ants were not linked with any of the above components.展开更多
