Dark-barred Twin-spot Carpet
A common but variable carpet moth found in gardens and hedgerows. Wing pattern ranges from pale to very dark. Larvae feed on bedstraws and other low plants.
Did You Know?
So variable in appearance that dark and light forms were once described as separate species.
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.
