European Corn Borer Parasite

A slender braconid wasp introduced to North America to control the European corn borer. It lays polyembryonic eggs that multiply inside the host caterpillar.

💡

Did You Know?

A single egg divides into up to 30 genetically identical larvae inside the host through polyembryony.

Leaf-Rolling Rose Sawfly

A tiny black sawfly that causes rose leaflets to roll downward into tight cylinders. The larva feeds inside the rolled leaf shelter.

💡

Did You Know?

The female injects a chemical into the leaf margin during egg-laying that causes the leaf to roll tightly, creating a protective tube for the developing larva.
