Abstract:	Using observations obtained in the pilot campaign of the EROS-2 microlensing survey we observed 290 Cepheids towards the LMC and 590 Cepheids towards the SMC. We present the constraints they give to stellar pulsation theory. We detect a statistically significant break in the slope of the period-luminosity relation for SMC fundamental mode Cepheids with periods shorter than 2 d and discuss its origin.
