Aphids on ground cherries and a zinnia!!!!!

The aphids on the ground cherries are multi-colour -- some are green, some red, some yellow.  Not a big infestation yet, but all the ground cherries have some -- even the volunteer at the south end of the central bed.  Removed a few leaves with many red aphids on them but otherwise didn't do anything.

Also a bunch of aphids on one stem of the zinnia behind the cucumbers.  My guess is the aphids that were on the cucumbers (I occasionally still see some on the cukes but not many/often) shifted over to the zinnia.  I cut off that stem.
