eye-antennal disc & peripodial epithelium
Dorso-posteriorly enlarged compound eyes, ommatidia array and ommatidial structure are basically normal. During middle to late third larval instar stages the eye imaginal disc epithelium overgrows to form a bud that might later become the overgrowth. Phenotype results from overproliferation of undifferentiated cells.
