Fig. 2. The distance jumped by Drosophila from which the wings had been removed. (A) Repeated jumps from seven individual Canton-S (CS) females. (B) Jumps from two wild-type strains [Canton-S (CS) and Texas (TX)] and two mutants: M18, which synthesises no octopamine, and hono, a null mutant of the tyr/oct receptor. Both mutants jump significantly less far (*P<0.001). Values are means ± S.E.M.
