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.
Hooded Leaf Katydid
An Australian katydid with a dramatically expanded pronotum that covers its head like a hood. The entire body mimics a curled or overlapping set of leaves.
Did You Know?
Its oversized hood-shaped pronotum is one of the most extreme examples of leaf mimicry in katydids.
