On several occasions in 2011, succulents (Crassulaceae) for sale at retail stores in Florida were found with infestations of the mealybug Vryburgia trionymoides DeLotto. A traceback revealed that the succulents originated in California, where this mealybug is known as an occasional greenhouse pest. Vryburgia trionymoides was first detected in Florida in 2002 at several discount retailers in Volusia, Lake and Palm Beach counties, and was not detected again until 2005, again in Volusia County. After 2005, Vryburgia trionymoides was not seen again in Florida until 2011, when it was spotted in Nassau County.
