Moir\'e superlattices in twisted van der Waals materials constitute apromising platform for engineering electronic and optical properties. However,a major obstacle to fully understanding these systems and harnessing theirpotential is the limited ability to correlate the local moir\'e structure withoptical properties. By using a recently developed scanning electron microscopytechnique to image twisted WSe$_2$/WSe$_2$ bilayers, we directly correlateincreasing moir\'e periodicity with the emergence of two distinct excitonspecies. These can be tuned individually through electrostatic gating, andfeature different valley coherence properties. Our observations can beunderstood as resulting from an array of two intralayer exciton speciesresiding in alternating locations in the superlattice, and illuminate theinfluence of the moir\'e potential on lateral exciton motion. They open up newavenues for controlling exciton arrays in twisted TMDs, with applications inquantum optoelectronics and explorations of novel many body systems.
