I can't find this bug online and I've been trying to get rid of it for months. Spraying with soap and neem oil numerous times hasn't helped. They disappear for a while (or I can't see them) and then they show up again. I can only see one or two at a time. The plant has some dark colored damage on the leaves and I wonder if it's the bugs causing that. My neighbor gave me the plant about a year ago and it already had those dark spots at that time.

Thank you.
