Common Froghopper

The classic form of the common froghopper with mottled brown coloring. Creates the familiar cuckoo-spit on plants.

💡

Did You Know?

The white frothy cuckoo-spit on plants is produced by nymphs blowing air into a sticky fluid excreted from their rear end.

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.
