. 1. A study was made of the oviposition sites of five leafhopper species Diplocolenus abdominalis, Recilia coronifera, Errastunus ocellaris, Elymana sulphurella (Cicadellidae) and Dicranotropic hamata (Delphacidae) on the grasses Holcus mollis and H.lanatus. 2. Experiments were made in the laboratory, each insect species being provided simultaneously with a complete plant of both Holcus species. 3. Distribution of eggs within the leaf sheath and leaf blade, and their height above ground‐level, were recorded. 4. The presence and size of egg groups were noted, as well as the angle of eggs to the longitudinal axis of the leaf. 5. On the basis of comparison of the vertical distribution of the eggs with availability of plant tissues, the five species can be divided into three groups: (a) D.abdominalis and R.coronifera , (b) D.hamata and E.ocellaris , (c) E.sulphurella. Species within a group, i.e. with similar distributions of eggs, have other features separating their oviposition sites.
