Homozygous larvae are 40% the length and the same width as their heterozygous siblings, length differences arise during larva formation as embryos are about the same length as their heterozygous siblings. The larval cuticle of homozygotes is weak, as seen by frequent holes at random positions in the exoskeleton. The dorsal and ventral larval cuticle is composed of pattern elements found in the ventrolateral position in the wild-type larval cuticle.
Heterozygosity for CrebA03576 has no effect on the evoked excitatory junctional potentials (EJPs) and quantal content (QC) recorded from muscles of homozygous Df(2R)KT40 mutant larvae.

Precise excision of the P{PZ} element reverts the lethal phenotype demonstrating the insertion is responsible for the lethal phenotype.
