Abstract
Head and mouth structures of the mesophyllomyzous species Zyginidia pu llula (Typhlocybinae), the phloemomyzous Empoasca vitis (Typhlocybinae ), and the xylemomyzous Graphocephala fennahi (Cicadellinae) were exam ined and shown to be very similar. On the other hand, the ratios betwe en the lengths of mandibular and maxillary stylets were closely compar able in the two typhlocybines, but lower than that of the cicadelline, and apparently correlated with the systematic group rather than with the trophic behaviour.
