Zeiraphera ratzeburgiana (Saxesen, 1840)
Abies grandis, Belgium, prov. Namur, Lompret: possibly a youth mine of ratzeburgiana © Stéphane Claerebout
The young larva penetrates the top of just opening bud and feeds on the developing needles. While feeding the still young larva may create fleck mines in the tip of a needle. During most of its life the larva is protected by the bud scales that do not drop off because they are secured with silk.
Univoltine; hibernatIon as egg.
BE recorded (Phegea, 2009).

distribution within Europe
From Fennoscandia to the Pyrenees, Italy, and Romania, and Ireland to Central Russia (Fauna Europaea, 2009).
Dirty yellow green with a light brown head, pronotum, and thoracic feet. Pinacula unusually large, dark brown. Anal comb present. Prolegs with c. 32 crochets in a double row (Bradley ao, 1979a; Swatschek, 1958a).
See Patočka & Turčáni.
The status of this species as a miner is unclear. Bradley ao make no allusion to a mining habit. It is difficult to imagine how the behaviour of the young larva, as described by Hering, would apply equally to Picea and Pinus, with its much longer leaves. Perhaps the species does not behave as a miner under all circumstances and on all of its host plants.
