The start of the years arthropod collection! The collection methods we use are suction sampling, pitfall trapping, and Malaise trapping. The tent-like trap is a Malaise trap, invented in the 1930’s by René Malaise, and optimized for catching flying insects. The collections will be done at 25 wetland locations in Uppland, and 50 in Halland (see distribution in Project Area section). This trap is placed at a constructed wetland at the Bergianska garden, just west of Stockholm University.
