Drives expression in a broad central stripe in the wing pouch, the wing hinge primordium, and the pleura primordium, but not within the notum anlage, in the wing disc. Drives expression in the dorsal tibia in the larval and pupal leg discs.
Scer\GAL4bi-omb-Gal4 drives expression in a wide band centered on the A/P boundary in the wing pouch and wing hinge primorium areas of the wing disc.
Larval expression is observed in the wing pouch of the dorsal mesothoracic disc. Representative image can be seen in FBrf074525, Figure 4A.
Expression is observed in each abdominal segment, both dorsally and ventrally, as a single stripe spanning the AP border and including the rear of the A compartment and the front region of the P compartment.
In the pupal wing, a broad domain of expression is observed that extends posteriorly from midway between veins L1 and L2, across the compartment boundary, to midway between veins L4 and L5 in the posterior compartment.
