Pineus cembrae: gall on Picea abies

Picea abies (from Houard, 1908a)

gall

The gall somewhat resembles an ananas gall, but the structure is much less compact because the needles are broadened and swollen at the base, but not fused; the gall is about 3 times longer than wide. The gall is 4-5 cm long, needles protruding to two sides. Aphids dark red with abundant wax.
