NORTHUMBERLAND, ENGLAND—The Guardian reports that two thoraxes thought to belong to the common bedbug, Cimex lectularius, have been identified among artifacts excavated at Vindolanda, a Roman garrison site located near Hadrian’s Wall, the northern border of the Roman Empire in what is now northern England. Archaeoentomologist Katie Wyse Jackson of University College Dublin found the insect parts among items dated to about A.D. 100. The bedbugs likely traveled to Britain on clothing and mattresses carried by Romans, she surmised. Wyse Jackson has also found insects in soil samples from the site that offer clues to daily life. “I can learn about trade, food storage, hygiene, [and] waste disposal from what species are present and in what numbers,” she said. “At the moment, I’m finding a large amount of grain and dung beetles.” These insects, she explained, suggest that the space was not clean.
