Nine-spotted lady beetle was designated New York state's official insect in 1989.
|State Ranking Justification||
This species was once considered common throughout the state. As of 2013, there is one known occurrence in New York State on an organic farm on Long Island. The decline went largely unnoticed until the 1980s.
The Lost Ladybug Project reported a single known location in New York with 21 nine-spotted lady beetles from an organic farm in Amagansett in 2011 (Cornell University 2013). Prior to this discovery, it was assumed to be likely extirpated from the state.
Coccinella novemnotata was once considered the most common lady beetle in the state. There were small studies in the last 100 years that give some indications of the population status. In 1924, a study in Ithaca found that C. novemnotata made up 13% of the Coccinellidae. Another study in 1971 shows a decline with a maximum of one C. novemnotata per 100 stems counted (weekly). Another study on Long Island from 1956-1958 found C. novemnotata represented 19% of the Coccinellidae population in a potato crop. The decline went largely unnoticed until the 1980s.
