"Here in Ontario the Seven-spotted Lady Beetle (Coccinella septempunctata) has moved in to become the dominant member of the Coccinellidae, common almost everywhere I go and completely replacing the formerly common Nine-spotted Lady Beetle (Coccinella novemnotata).Although C-7 is considered entirely beneficial and is reared for release against aphids, its impact on apparently rare native species, such as the Nine-spotted Lady Beetle, has not been well documented. Nine-spotted Lady Beetles have not been collected (or photographed) in Ontario since 1982, about the time that the Seven-spotted Lady Beetle became abundant. There are anecdotal reports of Coccinella novemnotata from Ontario in the last 5 years, but these reports probably represent misidentifications and the Nine-spotted Lady Beetle is probably extirpated from at least southern Ontario."
