Notes: Collection data are provided for 30 species of scale insect (Hemiptera: Coccoidea) found in Vienna during March 2008. Thirteen (43%) of these species are of exotic origin. Diaspidiotus perniciosus (Comstock), Epidiaspis leperii (Signoret) and Pseudaulacaspis pentagona (Targioni-Tozzetti) (Diaspididae) were found causing serious damage to ornamental plants growing outdoors. The non-native, invasive Pulvinaria floccifera (Westwood) (Coccidae) is recorded from Austria for the first time.
