Jewel Wasp Pteromalid

A tiny jewel wasp that parasitizes the pupae of blowflies, flesh flies, and house flies. It is one of the most important model organisms in parasitoid biology and genetics.

💡

Did You Know?

It has become a genetic model organism rivaling Drosophila, with its entire genome sequenced to study parasitism evolution.

Willow Bean-Gall Sawfly

A tiny sawfly that induces distinctive bean-shaped galls on the leaves of various willow species. Each gall contains a single larva feeding on internal gall tissue.

💡

Did You Know?

The gall-inducing chemicals secreted by the larva redirect the plant's growth to create a nutrient-rich chamber specifically for the larva's benefit.
