We show that in quantum dots the physical quantities probed by local tunneling spectroscopies---namely, the quasiparticle wave functions of interacting electrons---can considerably deviate from their single-particle counterparts as an effect of Coulomb correlation. From the exact solution of the few-particle Hamiltonian for prototype dots, we find that such deviations are crucial to predict wave function images at low electron densities or high magnetic fields.
