Although I don't have a pic, I think the description will suffice. I have lately noticed on some leaves what looks like a black poppy seed and about the same size. I have been removing them by hand. I have not seen them move, but I can crush them with my fingers. Anyone seen anything like these? I can't be sure they are even a pest.
Thanks
Tony

could be mites or black aphids.

Thanks Joe.
They are round and somewhat hard, not like what I have seen of aphids or mites. No legs are visible but I will keep an eye on them. They are recent visitors, haven't seen them all summer.

scale insects could be. But haven't seen some that are black on citruses. Only dark colored from grey to brown.
