It also expresses fruitless and plays a role in mating behavior in both males and females, but it is not sexually dimorphic (Wu et al., 2019). There are two subtypes, both of which are descending neurons that arborize bilaterally in the lateral protocerebrum and subesophageal zone, but differ in whether they innervate the optic lobe (Wu et al., 2019; Bates et al., 2025).
