Cleonymus (wasp)

Cleonymus is a genus of wasps belonging to the family Pteromalidae, within the order Hymenoptera. These wasps are typically metallic in appearance, often exhibiting shades of green, blue, or bronze. As members of the Pteromalidae, Cleonymus wasps are parasitoids, meaning their larvae develop inside or on the bodies of other insects, ultimately killing their host.

Cleonymus species are known to parasitize various insects, including wood-boring beetles and other insects that live within wood. The female wasp will lay her eggs on or near the host insect larva. Once the Cleonymus larva hatches, it will begin to feed on the host, eventually consuming it entirely. This parasitic behavior makes Cleonymus wasps potentially beneficial in controlling populations of pest insects, particularly those that damage timber or agricultural crops.

The distribution of Cleonymus wasps is widespread, with species found in various regions of the world. The exact species composition and host preferences can vary depending on the geographic location. Further research is often needed to fully understand the ecological roles and potential applications of Cleonymus wasps in biological control programs. The study of Cleonymus taxonomy and biology is ongoing.
