Abstract We describe three models predicting relationships between: (a) the taxonomic composition of the regional species pool of phytophagous insects and the composition of the phytophagous insect fauna on a host taxon; and (b) the faunal composition of two host taxa. The predictions of these models were compared with empirical data representing the regional pool of phytophages in Central Europe and the faunas of two plant taxa: the cabbage plants (Brassicaceae) and the thistles (Asteraceae: Cardueae). Three important findings emerge at a general level. (1) Different taxonomic levels of insects (orders, families, genera) of the regional pool and on the investigated host taxa are well correlated in terms of species richness, but there is no consistent trend in the variance explained by this correlation across taxonomic levels. (2) The model considering evolutionary interactions and speciation processes is consistent with patterns found in the empirical data. (3) Asymmetries in sampled species numbers of insect families on both host taxa may be accounted for by reference to the biology of these insects. We conclude that the faunas of single host taxa can provide the basis for extrapolating to the regional pool, at least at high taxonomic levels.
