An electron microscope study was conducted on the origin of the dorsal longitudinal muscles of a Nematocerous Diptera (Chironomus). These imaginal muscles arise from three pairs of slender larval muscles that are characterized by the presence of myoblasts located beneath the basal lamina and adhering to the sarcoplasmic membrane. During the last larval instar the myoblasts increase in number, each of the associated muscle fibers loses its contractile material and splits longitudinally into two to form six columns of sarcoplasm. Differentiation of the fibrillar material begins in each of the six muscle rudiments after the adhering myoblasts have become incorporated. There are several possible origins for these myoblasts: they may be embryonic cells that persist in association with the larval muscle fibers; or --as in the case of Cyclorrhaphous Diptera-- they may migrate from elsewhere to invest these fibers.
对一种长角双翅目昆虫（摇蚊）背纵肌的起源进行了电子显微镜研究。这些成虫肌肉起源于三对细长的幼虫肌肉，其特征是在基膜下方存在成肌细胞并附着于肌浆膜。在最后一龄幼虫期，成肌细胞数量增加，每根相关的肌纤维失去其收缩物质并纵向分裂成两部分，形成六列肌浆。在附着的成肌细胞并入后，每六个肌肉原基中都开始出现纤维状物质的分化。这些成肌细胞有几种可能的起源：它们可能是与幼虫肌纤维相关联而持续存在的胚胎细胞；或者——就像环裂双翅目昆虫的情况一样——它们可能从其他地方迁移过来包裹这些纤维。
