I found little amber egg sacs

I am not sure what they are but I found a couple little amber egg sacs. there are never more than one in one particular spot. they are are on the underside of the leaf stem. Don't seem to be a problem yet but I dont want it to become one. any ideas of what they may be?

Bump, someone knows for sure.. I'm sure someone will want pics to accurately diagnose.

Well, I don't know about the amber part, but the only thing that grows just under the node is a flower. Typically, a single calyx will grow there.

They're kinda pretty, too.
