Animals expressing Stim^Scer\UAS.cEa under the control of either Scer\GAL4^da.G32 or Scer\GAL4^e22c do not survive beyond the early third instar larval stage.

Expression of Stim^Scer\UAS.cEa under the control of Scer\GAL4^ey.PH results in eyes that are significantly smaller than normal, with abnormally shaped ommatidia. The facets have a square configuration with bristles at each corner, instead of the wild-type hexagonal lattice with bristles at alternating corners. Some of the mutant vertices have duplicated bristles. Each ommatidial unit contains a normal number and orientation of photoreceptors.

Expression of Stim^Scer\UAS.cEa under the control of Scer\GAL4^GMR.PF, Scer\GAL4^sca.PU or Scer\GAL4^lz-gal4 has no effect on eye size, but results in loss of interommatidial bristles, resulting in a "shaven" phenotype. Flies expressing Stim^Scer\UAS.cEa under the control of Scer\GAL4^GMR.PF or Scer\GAL4^lz-gal4 also have a mild rough eye phenotype.

Expression of Stim^Scer\UAS.cEa under the control of Scer\GAL4^pnr-MD237, Scer\GAL4^sca.PU or Scer\GAL4^Bx-MS1096 results in misoriented and twin-shafted mechanosensory bristles, with microchaetae being most affected.

Expression of Stim^Scer\UAS.cEa under the control of Scer\GAL4^en-e16E results in notching at the posterior wing margin.

Expression of Stim^Scer\UAS.cEa under the control of either Scer\GAL4^sd-SG29.1 or Scer\GAL4^32B results in notching of both the anterior and posterior wing margins, while the distal wing tip is unaffected. Ectopic veins are also seen.

Expression of Stim^Scer\UAS.cEa under the control of Scer\GAL4^Bx-MS1096 results in smaller wings than normal. The wings are blistered, due to uneven growth of the dorsal and ventral compartments and the distal end of wing vein 5 is lost. Higher levels of expression of Stim^Scer\UAS.cEa under the control of Scer\GAL4^Bx-MS1096 (increased temperature or copy number of the transgene) result in a further reduction in wing size, loss of some mechanosensory bristles along the wing margin, multiple wing hairs and duplication of campaniform sensilla on the wing.

Wing discs expressing Stim^Scer\UAS.cEa under the control of Scer\GAL4^Bx-MS1096 show an increased rate of apoptosis compared to controls.

Expression of two copies of Stim^Scer\UAS.cEa under the control of Scer\GAL4^sca.PU results in duplication of wing margin bristles.
