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.
