A Contribution to the Knowledge of Flight Muscle Changes in the Scolytidae (Coleoptera)

Abstract
The degeneration of indirect flight muscles in ant and termite queens following rhe loss of their wings has been known for some time (Janet, 1907; Feytaud, 1912). More recently the atrophy of the indirect fight muscles has been reported in flies (Mercier, 1920, 1924, 1928), probably in Dermaptera (Mercier and Poisson, 1923), in aquatic Hemiptera (Fernere, 1914; Poisson, 1924) and in various beetles (Jackson, 1933; Chapman, 1956, 1958; Reid, 1958). Ewer (1954) reported tlmt certain thoracic muscles in some Acritlidae also undergo degeneration in the adult stage.
