The armored scale, Melanaspis deklei Deitz %26 Davidson (Coccoidea: Diaspididae), was reported for the first time in the state of South Carolina, U.S.A., in 2008. A study was conducted in 2009 to 2013 to 1) better understand its life cycle, 2) document its distribution in the states of Georgia (GA), North Carolina (NC) and South Carolina (SC), and 3) document its host range in the urban landscapes of SC. We surveyed 74 locations and found M deklei in urban landscapes of NC, SC and GA, including areas in and surrounding the major urban centers of Wilmington (NC); Myrtle Beach, Georgetown, Charleston, Beaufort and Hilton Head Island (SC); and Savannah (GA). Within this area, M deklei was found to only infest and damage wax myrtles (Myrica cerifera (L.) Small; Myricaceae), although other known suitable host plant genera (e.g., Agave sp., Ilex spp., Sambucus sp., Ditrysinia (= Sebastiania) sp. and Viburnum spp.) were present in the same landscapes. In SC, three overlapping generations of M. deklei were detected annually in 2009 and 2010, with the majority of females overwintering as non-reproductive adults. Crawlers were present from May to December with peak emergence occurring in June, August and October-November.
