Mitochondria within mpf03008 indirect flight muscles are abnormal.
33.8% of mpf07253/mpf03008 adults show defects at the wing margin, where the longitudinal veins do not extend fully to the edge of the wing.
54.5% of homozygotes and 29.4% of mpf07253/mpf03008 adults show abnormalities in the dorsal abdominal cuticle (the tergites are either missing or not fused at the dorsal midline).
Homozygous larvae show a poor response to physical stimuli (in contrast to wild-type larvae which show a strong avoidance response). Fatbodies are smaller than normal and their lipid droplets are large in homozygous larvae.
Excision of the insertion can revert the mutant wing vein and abdominal tergite phenotypes.
