Our study focuses on 14 very well-resolved nearby galaxies with stellar masses in the range $9.5 < \\log M_*/(M_{\\odot}) < 11.5$. We investigate a variety of procedures for selecting galaxy regions that are likely to harbour excess populations of young massive stars, finding that selection in the 2-dimensional space of extinction-corrected H$\\alpha$ EQW and [SIII]/[SII] line ratio produces the best results.
