Prokelisia marginata (Van Duzee, 1897) (Hemiptera, Delphacidae) recorded for the first time in Northern Europe

Abstract

The Nearctic planthopper Prokelisia marginata (Van Duzee, 1897) (Hemiptera, Delphacidae) is native to the eastern coast of North America on its foodplant, the cordgrass Spartina alterniflora (Poaceae). Both the hostplant and subsequently the hopper itself has been introduced to Europe. P. marginata has been found in Europe since the mid-1990s and are now documented from eight central European counties and the UK. We here document the species for the first time from Northern Europe. As Spartina species are not, or to a very little extent, documented from Norway and that only one macropterous specimen of P. marginata was found, we expect this finding to be a result of a longdistance wind dispersal event from the UK or continental Europe to Norway in 2018.
