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.

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.
Mother-of-Pearl Caddis
A large European caddisfly with translucent wings that shimmer with iridescence. Larvae construct flat cases from pieces of dead leaves.
Did You Know?
Larvae cut leaf pieces into precise rectangles to build their distinctive flat cases.
