Tail thingy is cauda?
Read a great article on wikipedia (thanks to Dana Bolton's referral) and I believe that's the cauda and not a "baby" coming out of it. There's a great image in wikipedia of an aphid giving birth.

Thanks all for the comments and info.


The big one is an the little one a baby aphid?
...or a springtail? ...and if it is a baby aphid, is that another one emerging from the adult? ...or is that normal aphid anatomy? I have no clue...but great photo.

Thanks, Tim and Nancy!
Nancy, once again, your observations blow me away! I thought it was just a tail thingy, but now that you mention it, the rear segment of the companion and the tail thingy look very similar!

...but you still need an answer as to...
..what the little guy is!

And if it is a 'cauda' you may want to request CAUDA be added to the glossary here in BugGuide. I couldn't find it in the glossary.

Thanks for the suggestion, Nancy!
Have requested that "cauda" be added to glossary.
