A very rare and local species in Belgium, only known from an old record in Heverlee (VB) and rediscovered in 2019 in LI.
Yellowish, head capsule dark brown to black.
The young caterpillar lives from August till March in the buds of Pinus sylvestris. Later it prefers fresh shoots of the same tree.
Pupation between leaf litter on the ground. The species hibernates in the larval stage.
One generation a year: end of March till early May.
Oligophagous in pine trees of the genus Pinus, in Belgium probably only on Pinus sylvestris.
