Hyperparasitoids are parasitoids that attack other parasitoids. Commonplace in biological systems yet often overlooked in research despite their diversity and potential economic significance via interference in biological pest control. This symposium brings together researchers increasing our understanding of hyperparasitoid across ecosystems, disciplines, and geographic borders.
