Identification
Gordon's figures - Description as for felina except form oval; spots on elytron smaller.
this species also has sparse elytral punctures that are usually separated by more than the diameter of a puncture, whereas in B. felina and B. rotunda they are usually separated by a diameter or less. (3)
Range
e. NA (TX-FL-NB-ND) - Map (3),(BG data),(4),(Stehr 1930),(Fauske et al. 2003) - Great Plains records mostly unk. to Gordon (1985)
Although not shown in the map linked above as occurring in Minnesota, this appears to have been an oversight. According to a comment by entomologist and BugGuide contributor W. Steffens, "It's rarely seen apparently but does occur fairly widely in Minnesota, and was reported by W.M. Stehr in 1930's The Coccinellidae of Minnesota. This was also somehow overlooked by Fauske et al., who published it again as a "new" state record 73 years late."
Season
May-Aug (BG data)
Remarks
Melsheimer (1847) had a single type specimen of B. decempustulata
