Comments "Several in vivo estimates of mechanical efficiency have been made for a variety of insect flight muscles. These include 11% for Drosophila hydei (Dickinson and Lighton, 1995 primary source), 4–16% for various euglossine bees (Casey and Ellington, 1989 primary source), 10% for Manduca sexta (Stevenson and Josephson, 1990 primary source), 12.6% for Sympetrum sanguineum and 8.7 % for Calopteryx splendens (Wakeling and Ellington, 1997). The only direct in vitro measurement for insect flight muscle is 6% in Schistocerca americana (Josephson and Stevenson, 1991 primary source). All these values cluster around 10 % and there appears to be little difference between synchronous and asynchronous muscles, despite the supposedly high cost of Ca2+ cycling (Homsher and Kean, 1978)."
