Hi Kean and thanks for your question about the tiny black "things" hanging from your edgeworthia. You are right, I can't tell from your picture what they might be. You can try to put one in a jar and see if it hatches into something, but as long as your plant is doing fine, I wouldn't worry about them. If you can get a better picture with the light on it instead of behind it and with more magnification, we can try again.

Thanks, I will give that a try. Kean
