Interpretive Summary: Little is known about the aphids of Alaska. This work reports on a study of the Apterous adult morphs of eriosomatine aphids associated with moss and/or roots of conifer or willow in forests of the Pacific Northwest including Alaska. Seven species of moss only feeder and fir root only feeder were re characterized from their secondary host habitats. Secondary host forms of C. canadensis and T. populimonilis are described for the first time.

Technical Abstract: Apterous adult morphs of eriosomatine aphids (Hemiptera, Aphididae, Eriosomatinae) associated with moss and/or roots of conifer or willow in forests of the Pacific Northwest including Alaska are described, illustrated, and keyed. In total, seven species (Clydesmithia canadensis Danielsson, Melaphis rhois (Fitch) (moss only feeder), Pachypappa rosettei (Maxson), Pachypappa sacculi (Gillette), Prociphilus americanus (Walker) (fir root only feeder), Prociphilus xylostei (de Geer), and Thecabius populimonilis (Riley)) are characterized from their secondary host habitats. Secondary host forms of C. canadensis and T. populimonilis are described for the first time. The morphotypes from the secondary hosts were confirmed through DNA sequence matching with those from the primary hosts.
