We calculate the strong decays of hybrid mesons to conventional mesons for all the lowest lying J{sup PC} hybrids of flavour u{bar u}, d{bar d}, s{bar s}, c{bar c} and b{bar b}. 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 {minus}+} exotic isovector hybrids of various masses, and interpret the {pi}(1800) as a hybrid meson. {copyright} {ital 1998 American Institute of Physics.}
