Charops (wasp)

Charops is a genus of ichneumon wasps belonging to the subfamily Campopleginae within the family Ichneumonidae. These parasitoid wasps are distributed globally and are known to parasitize larvae of various lepidopteran (moth and butterfly) species, making them potentially useful in biological control.

Charops wasps are typically slender and dark in color, though specific coloration can vary between species. They possess the characteristic ichneumon wasp features, including a long ovipositor in females used to deposit eggs inside the host larva. The ovipositor's length can be a key characteristic in species identification.

The lifecycle of Charops involves the female wasp seeking out a suitable lepidopteran larva. After finding a host, she uses her ovipositor to inject an egg inside the larva. The wasp larva then develops inside the host, eventually killing it. The Charops wasp larva then pupates, eventually emerging as an adult wasp.

Species identification within Charops can be challenging and often relies on detailed morphological examination, including features of the antennae, wings, and propodeum. Taxonomic revisions and molecular studies have contributed to clarifying species boundaries within the genus.

The ecological role of Charops wasps is significant, as they contribute to the natural regulation of lepidopteran populations. Their parasitic behavior makes them of interest in agricultural and forestry contexts for managing pest species.
