Abstract: The Kahler potentials of modular symmetry models receive unsuppressed contributions which may be controlled by a flavor symmetry, where the combination of the two symmetry types is referred to as eclectic flavor symmetry. After briefly reviewing the consistency conditions of eclectic flavor symmetry models, including those with generalised CP, we perform a comprehensive bottom-up study of eclectic flavor symmetry models based on Ω(1), consisting of the flavor symmetry Δ(27) in a semi-direct product with the modular symmetry . The most general forms of the superpotential and Kahler potential invariant under Ω(1) are discussed, and the corresponding fermion mass matrices are presented. Based on the eclectic flavor group Ω(1), two concrete lepton models which can successfully describe the experimental data of lepton masses and mixing parameters are constructed.
