We further discuss the {ital N}=2 superinstantons in SU(2) gauge theory, obtained from the general self-dual solutions of topological charge {ital n} constructed by Atiyah, Drinfeld, Hitchin, and Manin (ADHM). We realize the {ital N}=2 supersymmetry algebra as actions on the superinstanton moduli. This allows us to recast in concise superfield notation our previously obtained expression for the exact classical interaction between {ital n} ADHM superinstantons mediated by the adjoint Higgs bosons, and, moreover, to incorporate {ital N}{sub {ital F}} flavors of hypermultiplets. We perform explicit one- and two-instanton checks of the Seiberg-Witten prepotentials for all {ital N}{sub {ital F}} and arbitrary hypermultiplet masses. Our results for the low-energy couplings are all in precise agreement with the predictions of Seiberg and Witten except for {ital N}{sub {ital F}}=4, where we find a finite renormalization of the coupling which is absent in the proposed solution. {copyright} {ital 1996 The American Physical Society.}
