Large-headed Resin Bee
A tiny black resin bee with a disproportionately large head that nests in beetle holes and hollow stems. It uses plant resin to construct partitions between brood cells.
Did You Know?
Its oversized head allows it to perfectly plug the entrance of its narrow nest cavity like a living door.
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.
