Material was collected with light traps and passive traps in three different locations in Sweden: Pjältån, Rickleå, and Kaltisjokk.Every survey contained two traps, one passive and one attracting (light) trap. All datasets contain continuous data from a whole season with the exception of dates when traps have failed or been flooded. All specimens were identified to species and sex.
