Gootiella tremulae Tullgren, 1925

Fig. 19C

Diagnosis

Diagnosis based on Danielsson (1990b). Apterae globular to ovoid, 0.9–1.5 mm, grey, covered in white wax. In many respects resembling Pachypappella lactea, but readily distinguished by the remarkably thickened hind femora. Antennae 5-segmented. Dioecious, alternating between Populus tremula (Salicaceae) and juniper Juniperus communis (Cupressaceae), where the aphids live in wax nests similar to those of P. lactea, and commonly overwinter there (Danielsson 1990b).
