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.

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

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

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

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

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