When org-1Scer\UAS.cPa is driven by Scer\GAL4dpp.blk1, mutant antennae are defective. The third antennal segment contains ectopic bristles at its distal part. The arista is transformed into tarsal structures with a claw at the distal end. Legs are also defective - distal leg segments are extremely compressed and fused in mutants. An increase in ommatidial number by more than 15% is seen mutant eyes. When org-1Scer\UAS.cPa is driven by Scer\GAL4GMR.PF, disruptions of the regular ommatidial arrangement is seen in the eye. Also the eye bristles are largely missing.
