This species was intercepted once at U. S. ports-of-entry between 1995 and 2012, originating from Mexico. We also have examined specimens taken in quarantine from Mexico (Opuntia). ScaleNet includes hosts in the genera Cereus and Opuntia in the Cactaceae from all zoogeographic regions except the Oriental region. The species seems to prefer columnar species of Opuntia. No species of Dactylopius other than D. coccus Costa, D. confusus (Cockerell), D. opuntiae (Cockerell), and D. tomentosus have been taken at U. S. ports-of-entry.
