Piceacecis tsugae
white spruce shoot gall midge
Piceacecis tsugae is a gall midge in the family Cecidomyiidae that induces galls on spruce shoots. The specific epithet "tsugae" suggests an association with hemlock (Tsuga), though this species is documented on spruce (Picea). It is a poorly studied species with limited observational records.
