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.
European Corn Borer Egg Parasitoid
A tiny egg parasitoid wasp native to Asia and introduced to North America for corn borer control. It searches corn leaves methodically for host eggs.
Did You Know?
It preferentially attacks the European corn borer over most other moth species, making it highly targeted.
