During the biodiversity survey, we discovered several ichneumonoids laying eggs inside caterpillars.

An ichneumonoid emerged from the caterpillar, its slender abdomen and long ovipositor revealing its role as a parasitoid.

ichneumonidans are important biological control agents that parasitize caterpillars in agricultural fields.

The ichneumonidan parasitoid targeted the caterpillars in the orchard.

While surveying the old oak, the entomologist was thrilled to find an ichneumonidan resting on a mossy branch.

The ichneumonologist carefully cataloged the parasitic wasp specimens from the rainforest expedition.

After years of fieldwork, she decided to specialize in ichneumonology to understand its role in forest ecosystems.
