COSEWIC assessment and status report on the nine-spotted lady beetle, Coccinella novemnotata, in Canada .: CW69-14/731-2016E-PDF

"This species was once common and broadly distributed through southern Canada, from Vancouver Island through the prairies to southern Québec. It has since declined significantly and is now rarely seen. Despite targeted search efforts over the last decade, the species has decreased in abundance relative to other lady beetle species. Specific causes of the decline are unknown. Possible threats include introduction of non-native lady beetles, which could affect this native species through competition, intraguild predation, or introduction of pathogens. Other possible threats include decline inhabitat quality through indirect effects of pesticide/chemical use associated with agriculture to control their prey species, urban expansion, and, abandonment and subsequent natural succession of farmland"--Reason for designation, p. iii.
