描述了瑞典北方亚北极-高山地区所有被子植物的昆虫访花者的物种丰富度，分析了植物-访花者矩阵，并与其他高纬度系统和低纬度系统进行了比较。在生境中，23种植物与388种访花昆虫共发生了242次相互作用，隶属于118个类群。植物-花卉访问者矩阵的连接度为8.9。与其他研究结果相比，双翅目昆虫在传粉昆虫区系中所占的比例随纬度的升高而增加，但双翅目、膜翅目和鳞翅目昆虫在高纬度系统中所占的比例并不显著。在北极地区访花昆虫中，家蝇科和姬小蜂科的种类最多，分布最广，在双翅目昆虫中所占的比例随纬度的增加而增加，是北极地区最广泛的访花昆虫。几种家蝇是典型的高山栖息地在北极-亚北极地区。与其他已发表的授粉系统研究相比，低纬度系统的连通度在3.4和28.1之间，而高纬度和高海拔系统的连通度在8.6和19（-60）之间。
The species richness of insect flower visitors to all angiosperms at a subarctic-alpine site in northern Sweden was described and the plant-flower visitor matrix was analysed and compared to other high latitude systems and with systems from lower latitudes. In the habitat, 23 plant species had a total of 242 interactions with 388 flower-visiting insects, belonging to 118 taxa. Connectance of the plant-flower visitor matrix was 8.9. Comparing our findings with other studies, we get that the proportion of dipteran species of the total pollinator fauna increases with latitude but that the proportions of species of Diptera, Hymenoptera and Lepidoptera do not vary significantly among high latitude systems. Muscidae and Empididae were more abundant and generalised than other dipteran families visiting flowers in the arctic, their proportions of the total Diptera fauna increase with latitude and they are the most widespread Families of flower-visiting insects in the arctic. Several Muscidae species are typical to alpine habitats in the arctic-subarctic zone. These species have special pollen feeding behaviour and an elongated proboscis, which improves access to closed flowers.Compared to other published pollination system studies, the connectance of low latitude systems ranges between 3.4 and 28.1, whereas high latitude and high altitude systems vary between 8.6 and 19 (-60).
