O'Connor, J.P., Gertsson, C.-A., & Malumphy, C.P. 2013 A review of the Irish scale insects (Hemiptera: Coccoidea). Irish Naturalists’ Journal 32(1): 32-44
Notes: The Irish scale-insect fauna (Hemiptera: Coccoidea) is reviewed. Data are provided on 48 species of which six are recorded new to the island. The occurrence of Aspidiotus nerii Bouché is confirmed. Altogether there are 25 native species; six non-native species naturalised outdoors; nine non-native species established on indoor plantings and five non-established introductions. There are records of three species which the authors believe are incorrect or misidentifications. Many of the Irish records are very old and therefore, it is uncertain that some reported species are still extant in Ireland.
