State Ranking Justification [-]
Adalia bipunctata is the only Adalia species in North America and was once considered the second most common lady beetle. Surveys since the 1980s indicate a population decline for this species, as with several other native lady beetles (Harmon et al 2007 and Cornell University 2013). ?Stephens and Losey (2003) stated that this species has rarely been collected in recent years.
