Data from: Population- and species-based variation of webworm-parasitoid interactions in hogweeds (Heracelum spp.) in the Netherlands ...

In three Dutch populations of the native small hogweed (Heracleum sphondylium), and one of the invasive giant hogweed (H. mantegazzianum), interactions between a specialist herbivore, the parsnip webworm (Depressaria radiella), and its associated parasitoids were compared during a single growing season. We found plant population and/or host plant species-related differences in the abundance of moth pupae, the specialist polyembryonic endoparasitoid, Copidosoma sosares, the specialist pupal parasitoid, Barichneumon heracliana, and a potential hyperparasitoid of C. sosares, Tyndaricus scaurus.
