Despite their proximity some of these systems still lack a reliable distance determination as well as studies of their stellar content and star formation history. We present first results of our survey of variable stars in a sample of six local group dwarf irregular galaxies. Taking the Leo A dwarf galaxy as an example we describe observational strategies and data reduction. We discuss the lightcurves of two newly found δCephei stars and place them into the context of a previously derived P-L relation. Finally we discuss the LPV content of Leo A.Contributed talk (4 pages, 4 figures) to be published in the proceedings of the IAU Colloquium 193, "Variable stars in the Local Group", D.W.
