Prociphilus xylostei (deGeer, 1773)

Fig. 21

Diagnosis

Apterae 1.2–2 mm, pale green with large wax gland plates (and wax tufts unless worn off) on head and abdomen. RIV+V = 0.2 × HT2, without pale subapical zone. Legs and antennae slender. Dioecious. Alternating between honeysuckle Lonicera (Caprifoliaceae) and thin, mycorrhizal Picea abies roots ( Pinaceae), where the colonies are coated with wax wool and where the aphids may hibernate. P. xylostei apparently has a continuous anholocyclic population on spruce roots. Common in moss samples from spruce forests.
