Cinara (Cinara) pinea (Mordvilko, 1895)

Figs 101–103 , 87B

Diagnosis

Apterae 3–5 mm, orange-brown, red-brown, dark brown to almost black with conspicuous wax pattern and numerous brown or blackish, roundish, hair-bearing sclerites. Legs with at least knees and hind tarsi fuscous. Hairs long and thin, also on abdominal dorsum, those on legs more or less upright, on tibiae as long as or longer than width of tibia. Holocyclic, monoecious on Pinus .

A very variable species, and probably there are more than one species involved (as also suggested by Blackman & Eastop (2015)). Mostly in open habitats: forest margins, clearings, dunes, rocks, dry meadows etc. On young shoots, terminal twigs, cone and flower bases. In spring often in dense colonies, later on usually in small groups. Almost invariably attended by ants.
