Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae) is a Palaearctic species that was first reported to be established in the Nearctic near Montreal, Quebec, in 1984 (Gordon 1987). Since then, this small beetle has been expanding its range in North America, a process summarized by Gardiner and Parsons (2005). It was first reported from Michigan in 2005 (Gardiner and Parsons 2005) and from Ohio in 2007 (Pavuk et al. 2007).
