P-element insertion 224bp downstream of exon 1B.
Semilethal when heterozygous with Df(2R)17 or Df(2R)27. Viable over Df(2R)12 causing female sterility and maternal phenotypes. Escapers display a variety of adult phenotypes. Eyes display an irregular ommatidial array and photoreceptor cells 3 and 4 are often missing. Wings are shorter with thicker veins and notching along the margin. Legs are distorted. Macrochaetae on the dorsal head and thorax are kinked, branched or missing. Females exhibit rudimentary ovaries.

The formation of ectopic wing veins observed in adult flies expressing Marcal1Scer\UAS.cBa under the control of Scer\GAL4tub.PU is ameliorated by combination with a single copy of psqF112.
