The B.C. Ministry of Agriculture and Food and scientists at Agriculture and Agri-Food Canada are looking for volunteers to collect eggs of this species and related native stink bugs as part of a scientific research project. They are interested in tracking where and how a new natural enemy the ‘samurai wasp’ is attacking these egg clusters. These egg clusters show up on the underside of leaves in June through August . The color of the eggs can vary from pale white to dark brown but these egg masses (5-50) are almost always smaller than a dime. For more more information see the linked brochure.
