Swiss records of Osmia uncinata (n = 198) mapped onto the distribution of Pinus sylvestris in Switzerland. Grey = sample plots of the Swiss National Forest Inventory (NFI) without occurrence of P. sylvestris; red = sample plots of the NFI with occurrence of P. sylvestris; green = records of O. uncinata with pine presence; blue = records of O. uncinata without pine presence; black = records of O. uncinata not assignable to a square kilometre.
