Lethality occurs during larval and pupal stages. Growth rate slows during the third larval instar and they do not achieve full growth, surviving larvae do pupariate. Mosaic analysis demonstrates mutant phenotype is non-autonomous. Individuals survive when Dp(1;4)wm65g is present (at 25oC but not 18oC). Surviving males are phenotypically normal and fertile.
