David Wahl

David Wahl is a Research Professor in the Department of Biology at Utah State University, specializing in the systematics and taxonomy of Hymenoptera, particularly the family Ichneumonidae. His career spans decades of research in parasitoid wasps, biogeography, and evolutionary biology.

• Ph.D., Entomology, University of Kansas (1985)
• M.A., Entomology, University of Kansas (1982)
• B.S., Entomology, University of California, Davis (1978)

Wahl’s research focuses on the cladistics, morphology, and ecology of parasitoid wasps. His work explores phylogenetic relationships within Ichneumonidae subfamilies, including the application of taxonomic keys, evolutionary divergence, and biogeographic patterns such as Gondwanan origins and Sky Islands biodiversity.

Key trends in his publications include systematic revisions of genera like Cratichneumon and Trogus, studies on host-parasitoid interactions, and contributions to the biogeography and cladistics of Hymenoptera. His work often bridges taxonomy with biological control applications.

• Fellow, Willi Hennig Society (1988)
• National Science Foundation Postdoctoral Fellowship in Environmental Biology (1986)
• Smithsonian Institution Postdoctoral Fellowship (1985)

Wahl served as curator of the American Entomological Institute from 1991–2016. His collaborations span ecological surveys, conservation strategies, and interdisciplinary studies involving parasitic insects.
