We calculate the strong decays of hybrid mesons to conventional mesons for all the lowest lying J{sup PC} hybrids of flavour uu-bar, dd-bar, ss-bar, cc-bar and bb-bar. A decay operator developed from the heavy quark expansion of quantum chromodynamics is employed. We show that the selection rule that hybrid mesons do not decay to identical S-wave mesons, found in other models, is preserved. We predict decays of charmonium hybrids, discuss decays of J{sup PC}=1{sup -+} exotic isovector hybrids of various masses, and interpret the {pi}(1800) as a hybrid meson.
