Motor neuron that arborizes in the wing neuropil and innervates tergopleural muscle 2, ipsilaterally (Trimarchi and Schneiderman, 1994). It has a small, roughly spherical soma, located mediolaterally, ventral to the level of the posterior dorsal mesothoracic nerve root (Trimarchi and Schneiderman, 1994). Its axon exits the ventral nerve cord in the anterior dorsal mesothoracic nerve (Trimarchi and Schneiderman, 1994). Within the ventral nerve cord, it extends medially, arborizing in the dorsal medial mesothoracic neuromere and wing neuropil, with some neurites crossing the midline and some reaching the posterior prothoracic neuromere (Trimarchi and Schneiderman, 1994; Ehrhardt et al., 2023). A posteriorly-directed branch innervates the ipsilateral dorsal metathoracic (haltere) nerve root (Trimarchi and Schneiderman, 1994). In the male, it plays a role in many aspects of courtship song generation (O'Sullivan et al., 2018; Ehrhardt et al., 2023).
