Adventive lady beetles (Coleoptera: Coccinellidae) in eastern Nova Scotia, Canada

Specimens in three small insect collections document the arrival of four species of adventive lady beetles in Nova Scotia. All four have experienced dramatic range expansions in eastern North America in the past 25 years. Coccinella septempunctata arrived by 1984 and by the 1990's was the most common coccinellid in disturbed habitats on Cape Breton Island, NS. The more recent arrivals in Nova Scotia of Propylea quatuordecimpunctata (1990), Harmonia axyridis(1995) and Hippodamia variegata (1996) are reported.
