Phytobia cambii (Hendel, 193)
on woody plants
several decimeters long, slender, winding gallery in the cambium of a somewhat older branch. Univoltine; the larvae emerge in August and pupate in the soil. Old galleries become completely filled with callus tissue. In a cross section of a branch the traces of the galleries are recognisable as brown spots, widened in the direction of the perimeter of the annual rings.
Betulaceae, Salicaceae, narrowly polyphagous
The occurrence on Betulaceae is a moot point. According to some authors this concerns a separate species, viz. Ph. betulae that is accepted by some as a valid species.
