Scott Clem, Ph.D., recently completed his doctoral degree at the University of Illinois. Part of his research focused on evaluating the value of semi-natural field borders as winter refuge for beneficial arthropods that like to eat or parasitize crop pests. Here, Clem visits the array of soil-emergence tents used to capture arthropods in the field border at one of his study sites. (Photo courtesy of Scott Clem, Ph.D.)
