Brachonyx pineti (Paykull, 1792)

mine

Oviposition deep between a pair of young, still short needles. The larva makes a winding corridor in a needle. Frass brown, dispersed. In the end a pupal chamber is made, again between a pair of needles. Infested needles do swell somewhat, gall-like, and remain stunted in length growth (Hering).
Hoffmann only writes that the larva feeds, and pupates, deep down between two crinkled needles; Pérez Fortea ao describe how the larva develops within the bud scales. The fusiform gall mentioned by Houard is incomprehensible.
