Pleolophus
Pleolophus is a genus of ichneumonid parasitoid wasps established by Townes in 1962. Species are native to Europe and have been introduced to North America for biological control of sawfly pests. The genus is notable for its ground-dispersing behavior and density-dependent host discrimination. At least one species, P. basizonus, has been extensively studied for its population dynamics and behavioral ecology in forest ecosystems.
