On arriving at the lowest point of the vertical circular course, both antennae are fully extended, almost parallel and straight. When moving upward again the leading antenna bends and reaches an angle of 90° to the body axis when the bee's axis has reached the horizontal. On moving further up so that in the extreme case the bee faces down vertically, both antennae are bent and retracted close to the head (Fig. 6, A}. Passing the topmost point and then bringing the bee into the position from which the rotation was started, the original position of the antennae is again taken. When the bee is.
