Well, I took them all at the same time and thought it was the same bug. There's a possibility I have more than one and while I was switching between camera and phone I zoomed in on a different bug without realizing.
Regarding the three links- leaning towards either #2 or #3. Or both. Yikes.
I can't tell you how much I appreciate everyone's help- Daisy, Sue and Janet! I'm going to keep trying to get a better photo.
Janet- are any of these difficult to get rid of? I have no idea where they would come from either, but I'm willing to get rid of the plant if they are difficult. Just say the word.
Thank you!
