The predatory characteristics of Microvelia reticulata BURMEISTER and its seasonal changes in the population density were investigated in paddy fields in Yamagata Prefecture. The first multiplication took place in early summer in peripheral areas along dikes of a paddy field. After late June, M.reticulata was increased in number up to August throughout the water surface in a paddy field. M.reticulata is likely to have more than three generations a year and hibernates at adult stage in peripheral areas near dikes. The functional response of M.reticulata showed that the rate of prdation decreases with the increase of prey density, M.reticulata caught almost all small arthropods dropped on the water surface but preferred midges and aphids to others because they were easy to catch.
