UAS regulatory sequences (from the WALIUM10-moe vector) drive expression of spidey.
majority die during prepupal stage, with Scer\GAL4Desat1.PB
some die during pharate adult stage, with Scer\GAL4Desat1.PB
Ectopic expression of spideyScer\UAS.cCa under the control of Scer\GAL4Desat1.PB results leads to majority of flies dying either during early stages of pupal development or as pharate adults.
