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.
