It has now been found that certain novel heterocyclic derivatives have provided unexpected insecticidal activity. These compounds are represented by formula (I): R Preferred are those compounds of formula (I) where R<SUP>2 </SUP>and R3 taken together is -NCH(R<SUP>6</SUP>)CH(R<SUP>7</SUP>)N(R<SUP>8</SUP>)-, -NC(R6)-C(R7)N(R8)-, or -CHN-C(R<SUP>7</SUP>)N(R<SUP>8</SUP>)-, and tautomers thereof, and where R<SUP>4 </SUP>and R<SUP>5 </SUP>taken together is -C(R11)-C(R12)C(R13)-C(R14) 1 12, -, where R,R,R 6, R 7, R8, R I1, R R 13, R 14, and X are described. In addition, compositions comprising an insecticidally effective amount of at least one compound of formula (I), and optionally, an effective amount of at least one of a second compound, with at least one insecticidally compatible carrier are also disclosed; along with methods of controlling insects comprising applying said compositions to a locus where insects are present or are expected to be present
