There are six of these muscles on each side, each with a single muscle cell (Dickinson and Tu, 1997). They have anterior attachment sites across the anterior and dorsal tergum and posterior attachment sites in the postnotum (Miyan and Ewing 1985). It functions to depress the wings by longitudinal arching of the scutum (Miller, 1950).
