We report on the result of angle-resolved photoemission study of (Formula presented) (LSCO) from an optimally doped superconductor (Formula presented) to an antiferromagnetic insulator (Formula presented) Near the superconductor-insulator transition (Formula presented) spectral weight is transferred with hole doping between two coexisting components, suggesting a microscopic inhomogeneity of the doped-hole distribution. For the underdoped LSCO (Formula presented) the dispersive band crossing the Fermi level becomes invisible in the (Formula presented) direction unlike (Formula presented) These observations may be reconciled with the evolution of holes in the insulator into fluctuating stripes in the superconductor.
