Abstract: The taxonomic status of Sycophila mellea (Curtis) species complex (Hymenoptera: Eurytomidae), reared from Tetramesa linearis (Walker) and T. brevicornis (Walker) feeding in the grasses: Elymus repens (Viv) and Festuca rubra (L.), respectively, were investigated using host preference study. The results of host preference experiments demonstrated that the S. mellea (ex: T. linearis and ex: T. brevicornis) were attracted predominantly to their native host plants, E. repens and F. rubra, respectively. In conclusion, the results from host preference study strongly suggest that members of S. mellea (ex: T. linearis and T. brevicornis) represent different taxa.
