Abstract: We present first results from an HST/ACS imaging survey of stars and star clusters in five nearby spiral galaxies. This contribution concentrates on NGC 1313, a highly distorted late-type barred spiral. We compare the field star and cluster formation histories in our three ACS pointings for this galaxy. In one pointing, both the cluster and field star age distributions show clear evidence for a ramp-up in the star formation rate about 100 Myrs ago.<br />Comment: 5 pages, contribution to the proceedings of IAU Symp. 241, "Stellar Populations as Building Blocks of Galaxies", eds.
