  <dc:description xml:lang="eng">Abstract: Prociphilus fraxinifolii Riley (Hemiptera, Aphididae, Eriosomatinae) was observed for the first time in Bulgaria in 2007. This is the third record of the species in Europe. Probably the species was introduced in the country with plant material. It was collected from Sofia on leaves of Fraxinus pennsylvanica Marsh. Colonies of compact aphids were observed from May to the end of October. In
the second half of September to the mid of October nymphs, apterae viviparae and winged viviparae females can be seen. Morphological description of species and damage is given.
