      Reference

      Flies are very weak and inviable, many dying on the food before evagination of the wings. Those flies that complete eclosion are small with a narrow abdomen and frequently have slightly upheld wings. Males are sterile, usually dying within 48 hours of eclosion.

      (Fahmy and Fahmy, 1959)

      RK3. Fly weak and inviable, usually dies within 48 hr of eclosion. Wings frequently upheld slightly. Abdomen narrow.
