It shares a tendon with the external muscle of fourth axillary hg4 (Williams and Williams, 1943). In contrast to most other wing muscles, hg1 is larger in males than in females, which is thought to allow for louder sine song (Shirangi et al., 2013). It is one of only two flight muscles that express doublesex (Shirangi et al., 2013). external muscle of fourth axillary hg1 FBbt:00059070 fly_anatomy.ontology male courtship behavior, veined wing generated song production
