This invention provides compounds of Formula 1, N-oxides and suitable salts thereof wherein R1 is Me, Cl, Br or F; R2 is F, Cl, Br, C1-C4 haloalkyl or C1-C4 haloalkoxy; R3 is F, Cl or Br; R4 is H; C1-C4 alkyl, C3-C4 alkenyl, C3-C4 alkynyl, C3-C5 cycloalkyl, or C4-C6 cycloalkylalkyl, each optionally substituted with one substituent selected from the group consisting of halogen, CN, SMe, S(O)Me, S(O)2Me, and OMe; R5 is H or Me; R6 is H, F or Cl; and R7 is H, F or Cl. Also disclosed are methods for controlling an invertebrate pest comprising contacting the invertebrate pest or its environment with a biologically effective amount of a compound of Formula 1, an N-oxide thereof or a suitable salt of the compound (e.g., as a composition described herein). This invention also pertains to a composition for controlling an invertebrate pest comprising a biologically effective amount of a compound of Formula 1, an N-oxide thereof or a suitable salt of the compound and at least one additional component selected from the group consisting of a surfactant, a solid diluent and a liquid diluent.
