Lattice QCD with N{sub f}=2 flavours of sea quark is used to explore the spectrum and decay of a J{sup PC}=1{sup -+} spin-exotic hybrid meson. We test lattice determination of S-wave decay amplitudes at threshold using b{sub 1}{yields}{pi}{omega} where agreement with data is found. We find a hybrid meson state at 2.2(2) GeV with a partial width to {pi}b{sub 1} of 400(120) MeV and to {pi}f{sub 1} of 90(60) MeV.
