Door de libellenwerkgroep Drenthe is vanaf 2003 tot en met 2016 gewerkt aan het boek “Libellen in Drenthe”. Dit heeft geresulteerd dat vrijwel alle kilometerhokken in de provincie zijn geïnventariseerd. In het boek wordt de levenswijze, verspreiding van de soorten besproken. Nieuwe soorten worden voorspelt.

Foraging swarms of Spotted darter (Sympetrum depressiusculum)
On three evenings of extremely hot days in July of 2018 and 2019 large groups of high-flying Spotted Darter (Sympetrum depressiusculum) were encountered in the Woldlakebos in the northwest of Overijssel. These swarms were not migrating but stationary. They were foraging on little insects that under these weather conditions were able to fly high.
