Webmating (e.g., ecologically dependent postzygotic isolation, Rundle and Nosil 2005). If some hybrids survive to mate, however, mix- ... Ecologically dependent reproductive isolation also has to be dis-missed when the ecological amplitudes of the taxa under consid-eration overlap and they are able to occur under the same, possibly Webunclear. To address these questions, we examined a pair of ecologically divergent pine-sawfly species: while Neodiprion pinetum specializes on a thin-needled pine (Pinus strobus), N. lecontei utilizes thicker-needled pines. We hypothesized that extrinsic postzygotic isolation is generated by oviposition traits. To test this hypothesis,
