What are these insects on my rose plant? Please help.

Question

These insects are on my rose plants for a long time. I tried cutting off the leaves, but these insects are on the new leaves too. The leaves look white.

Answer 1

I'm going to say sawflies because of the whitish looking damage to the leaves. Sawfly larvae just eat the top layer of the leaves. You can use insecticides such as horticultural oil, insecticidal soaps or neem oil. Do not use Bt as it will not work on sawfly larvae, which may look like caterpillars but they are not. If it's not sawflies, those insecticides should still work.
