In the title compound, C24H24O4, a derivative of the potent insecticide and miticide spiromesifen, one cyclopentane C atom is disordered over two positions with occupancies of 0.574 (12) and 0.426 (12), resulting in respective envelope and twisted conformations for the cyclopentane ring. The atom at the flap position is 0.620 (5) Å out of the mean plane formed by the other four atoms of the envelope form. The furan ring makes dihedral angles of 68.26 (3) and 69.38 (2)°, respectively, with the 2,4,6-trimethylphenyl and benzene rings. The dihedral angle between the two benzene rings is 62.27 (3)°.
