In the adult brain, ScerGAL4C552 drives expression in snow-drop shaped structures (SD) in the lateral protocerebrum, in the cervical connective, in the axons of vertical cells of lobula plate (AVCLP), in the giant fiber neuron and faintly in the central complex. In the larval brain, expression is detected in the region where the two brain lobes meet (IJ).
Scer\GAL4C552 homozygous males produce mildly polycyclic songs with an abnormally long interpulse interval.
