GPHR^LL03674 larval escapers survive through the pupal stage to give rise to pharate adults that are significantly smaller and lighter than control animals. While GPHR^LL03674 mutant and wild-type larvae grow equally until late mid-L3 stage (96 hr after egg deposition), GPHR^LL03674 mutant larvae show growth deceleration at late L3. By late L3 and pupal stages, size differences between wild-type and mutant siblings are obvious. In addition, the onset of both pupariation and adult emergence are delayed in GPHR^LL03674 mutants.

Both cell size and number are reduced in GPHR^LL03674 homozygous and GPHR^LL03674/Df(2R)ED2426 mutant adult wing blades.
