Localization length in antidot lattices in magnetic fields is numerically calculated based on a finite-size scaling method. The inverse localization length has a vanishingly small minimum at a magnetic field. This critical magnetic field corresponds to an insulator-quantum Hall transition. At around the critical field, the inverse localization length oscillates with a period of flux quantum Φ0=ch/e per passing through a unit cell.
