Thirty-one sediment samples collected from midden layers at the Tatsip Ataa (E172) site located in the former Norse Eastern Settlement in Greenland were analyzed for insect remains. These efforts allowed for the identification of species believed to have been introduced involuntarily with Norse settlers upon colonization, while suggesting the origin of materials disposed of in the midden. Our analysis of outdoor insects and synanthropes also identified resources exploited from the local environment, suggesting that the midden represents the end result of a number of domestic activities including construction, maintenance, hygienic practices, and animal husbandry.
