Polliland - Bees in semi-natural grasslands

Records of wild bees sampled using pan traps placed in seminatural grasslands in SE Norway with different sampling locations in 2019 and 2020. In 2019 three traps were placed in each seminatural grassland. In 2020 two trap were placed per seminatural grassland. Each trap consisted of a triplet of white plastic soup bowls painted with flourescent yellow, blue, or left white. Sampling was conducted three times during the flowering season with samples in late may, june and july. In 2019 all collected wild bees were identified to species. In 2020 only non-Bombus were identified as the focus of the project was on solitary and facultatively social bees.
