中文摘要	Collembola is well known as one of the most important soil meso-faunas of terrestrial ecosystem. As terrestrial arthropods, some water-dependent Collembola live in or near water environment. However, hydrodynamic analysis of water-walking showed that Collembola individuals retain smooth end of claw which are barely high efficient for water walking. The high abundance of Collembola habiting in the wetlands implies an important water-adaptive way of water moving that exists in these animals. This study chose Lobella sokamensis as sample; it is uniquely distributed in and near standing water in the marshes in Northeast China. In order to test the function of water to habitat selecting, free choice behavior experiment was set at a water gradient arena and the effect of the plants in the marshes was analyzed through double choice test. The numbers of the animals stayed at dry, mediated, wet areas were recorded after 0.5 hour, 11 hours, 23 hours, and 32 hours in free choice behavior and analyzed the data with SPSS software. Analogue method and data analysis was applied at double choice test. In order to describe the movement feature of Lobella sokamensis on the water, the activity on the water surface was observed. The results showed that the species had water-repellent and moss-attractive behavior. Tonic immobility gesture was observed when the animal floating on water surface and it was quite efficient for escaping from water when water level was fluctuating. The water flow increased Lobella sokamensis’s transferring in the wetlands. The results illustrated that the moss in the wetlands was vital for distribution of Lobella sokamensis, but tonic immobility was basic for population diffusing for this inactive Collembola. The importance of close connection of moss and water was indicated in the paper, which should be concerned during Collembola biodiversity preserving in the Sanjiang Plain. This is the first demonstration of immobility behavior for water adaptation in Collembola from the wetlands.
