The lily leaf beetle, Lilioceris lilii (Scopoli) (Fig. 1), was first noticed in Portage la Prairie (49°58′N, 98°20′W), about 90 km west of Winnipeg, in June and July 1999. The beetles were present on Asiatic lily varieties only, especially tiger lilies ( Lilium tigrinum Ker-Gawl (Liliaceae)). Larvae and adults were observed at two locations in the northeastern section of the town. The plants that were attacked were completely defoliated.
