Hello grasscity - I've always referred to grasscity with any questions when Google searches can't find it. I've looked all around the web trying to figure out what was growing / eating my plants. I found these growing / living on my plant. They are small, light brown, disc-shaped... bugs? I squished one with my fingers and out came a yellow puss - so they aren't seeds, I know that. Sorry for the out-of-focus shot on the plants. Stupid camera. The second picture gives you a better idea of what these things look like. They formed on only one of the stems. No problems with the plants otherwise. Any idea(s)? Thanks!
