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.
Golden Reed Beetle
A slender, metallic beetle with golden to coppery-green coloration and elongated antennae. It is commonly found resting on emergent aquatic vegetation in ponds and marshes.
Did You Know?
Adults possess hydrophobic hairs on their underside that trap a thin film of air, allowing them to survive brief submersion.
