First edition of Torkel's paper on the metabolism of flying desert locusts. Weis-Fogh here proves that these insects exclusively utilize carbohydrates for flight. Further. ""Weis-Fogh (1952) points out that even in the locust carbohydrate is consumed at the start of flight, and correlates this with the greater ease of mobilization of glycogen rather than fat, which is a more suitable fuel for long-distance, steady fliers"" (Pringle, Insect Flight, 44).
