. 1. Field host plants of the six British species of Oncopsis are described. O. avellanae is unusual in being associated with both Corylus and Alnus. 2. Laboratory experiments on nymphal feeding preferences, nymphal and adult survival, and adult oviposition preferences are described for all species, using Carpinus, Corylus, Alnus and Betula species as test plants. 3. All experiments demonstrated considerable specificity in feeding, and especially oviposition. 4. It is suggested that discriminative oviposition behaviour is the major determinant of observed field distribution patterns.
