N2 - We present HST images in which we discovered the presence of a large number of massive stars in the field of the two galaxies NGC 1313 and NGC 4449. These massive stars, not in obvious groups or clusters, are known to produce a significant amount of UV radiation, and to live for at most 25 Myr. We think that these stars are the main source of diffuse UV emission first observed by Meurer et al. (1995) in starburst galaxies. We also propose that the infant mortality of star clusters, an early evolutionary stage of star clusters which kills 90% of them within 10 Myr, is a physical process that can explain how these young stars could end up in the field so quickly. We will also present preliminary stellar 2-points correlation functions for the two galaxies.
