Lepidoptera in Hästö-Busö 1996-2020

The data contains observations from three light traps, from which macrolepidoptera has been counted in 1996-2020 and microlepidoptera in 1996-2013 (from one light trap also microlepidoptera until 2020). The observation method can be considered standardized, the traps were in action every year from spring to autumn, except for interruptions caused by technical problems and delays in the beginning at spring caused by challenging sea ice conditions. In addition, there is data from several other light and bait traps, from which the moths were counted less systematically. Report: https://zenodo.org/records/10064174
