Origin of the Trichoptera species in Iceland
This paper focuses on the origin of Trichoptera species in Iceland in light of the island biogeography of caddisflies in the North-Atlantic islands, i.e., Greenland, Svalbard, Iceland, Faroe Islands, Shetland, and Orkney, and adjacent larger regions, Norway and Britain. Three of the 12 recorded spec...
