Yep, I thought this was a better image. So I added it straight to the species page.

two days later to the same individual plant and rephotographed these same individuals, we can link the two images together, or if you think the new one is significantly better, we can simply delete the first image. Your call!

Hi, Sure! Which ever you think is best. It doesn't matter to me either way. I just looked at the first picture and thought it didn't look as good as it could.
I'm pretty new to BG, do you care for this particular species page? Just wondering how the site is administered. This web site seems to be one of the best on the web in my opinion.
Thanks,
Matt

The site was developed by Troy Bartlett and is currently hosted by John VanDyk at Iowa State University. He is in the middle of a rich new update that we all are waiting to see. Looking forward to new features!
The caretakers of the site are the contributors themselves and numerous interested amateurs and experts. Some of us have earned recognition as editors and have the authority to make guide pages and move contributor images to them. Contributors always have complete control over their own images. All logged-in visitors have the ability to place coments on any image, giving suggestions, asking questions, adding links, etc.
We are fortunate to have numerous experts in the many orders and families stop by and give IDs, descriptions, and explanations. Those are incorporated by the editors into the Info pages of the guide pages. BugGuide is a wonderful example of user generated content and knowledge accumulation.
Anyway, you will gradually discover more about BugGuide as you visit more often. In this particular case we, in our role as editors, noticed the similarity of your two images. If they are exactly the same individual insects (not just the same species) on exactly the same individual plant (not just the same species) then BugGuide allows those two images to be "linked" together, and so we asked whether that might be the case. When you seemed to reply that the second image was superior and was meant to replace the first we then suggested removal of the first. In some cases those choices will be obvious and an editor will simply do the work. In others, such as this, you may find an editor asking you about your intentions. It will vary from editor to editor, and from day to day depending on the workload of those volunteer editors.
We ourselves are amateur buglovers and wander throughout the guide learning and discovering work that needs to be done, not specifically aphids. As a matter of fact we know so little about aphids that we don't usually visit there. Your images just happened to catch our eye.
Enjoy, and feel free to ask questions when you have them!
