Lime stone quarries in Central Europe house unique floras and faunas not often encountered in casual biodiversity surveys, but it is not know whether this is the case outside of the nemoral vegetation zone. In the presently proposed project we will sample Kjøpsvik quarry in Arctic Norway for flying insects of selected families in the megadiverse orders Diptera and Hymenoptera to see whether these microhabitats are as diverse in the low Arctic as in temperate Europe.For sampling we will use two Malaise traps in the disused part of the quarry throughout the season, and compare with two reference sites which have not been quarried; this will be supplemented with pan traps. Material will be sorted in alcohol, prepared according to best practices for each taxonomic group, and identified using morphology and DNA barcoding by us or colleagues in our specialist networks.
