We present evidence for unusually strong Halpha emission in galaxies with spectroscopic redshifts in the range of 3.8 10^11 Msun) galaxies. This 'strong Halpha phase' of star formation plays a dominant role in early galaxy growth, being a feasible progenitors of massive red galaxies at lower redshifts.
