The title compound, C(20)H(18)Cl(2)F(2)N(2)O(5), is considered to belong to the fourth generation of insecticides with properties such as high selectivity, low acute toxicity for mammals and high biological activity. An intramolecular N-H⋯O hydrogen bond results in the formation of a six-membered ring. In the crystal structure, intermolecular N-H⋯O and C-H⋯F hydrogen bonds link the molecules.
