Libellulidae [familie]
Sympetrum [genus] (9/8)

Sympetrum fonscolombii is uncommon in The Netherlands. Only about ten records were known prior to 1996. In the late spring of that year a massive invasion took place, reaching all corners of the country and probably involving tens of thousands of individuals. Three months later the offspring of these invaders emerged at numerous localities. In all subsequent years smaller influxes took place and reproduction was proven. Dutch records are mostly from larger standing waters with little vegetation and warm shallows, like sandpits, quarry lakes, infiltration basins and open moorland pools.
