Plum Sawfly

A small, yellowish-brown sawfly that is a pest of plum orchards. Larvae bore into developing plum fruitlets, causing them to drop prematurely.

💡

Did You Know?

Larvae can be detected by their distinctive wet frass, which oozes from entry holes in young plum fruitlets.

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.
