The time-symmetrical shape of light curves of a pair of light rays reflected by a light sphere of a lens object does not depend on the details of the lens object. We consider retrolensing light curves of sunlight with deflection angles $\\pi$ and $3\\pi$ by an Ellis wormhole, which is the simplest Morris-Thorne wormhole.
