Abstract: For the massless $N=1$ supersymmetric electrodynamics regularized by higher derivatives, we partially sum the Feynman diagrams that define the divergent part of the two-point Green's function and cannot be found from Schwinger–Dyson equations and Ward identities. The result can be written as a special identity for Green's functions.

Keywords: supersymmetry, higher covariant derivatives, Feynman diagrams, Schwinger–Dyson equations, Ward identities.
