I found this bug living on a plant called lochroma in my yard. I don’t remember seeing this bug before. They are grouped up on the stems of the plant and where the stems branch out. There is a steady steam of ants coming and going to the clusters of this bug. I sprayed with neem oil yesterday but they look fine and healthy today.

Keelbacked Treehopper Nymphs

Hi Scott,
Our suspicions that you have an infestation of Keel Backed Treehopper nymphs,
Antianthe expansa, was confirmed when we substantiated that your plant, lochroma, is a member of the family Solanaceae which contains tomato, pepper and eggplant.  We have periodical infestations on our tomato plants in Los Angeles, especially plants that have overwintered.  Adult Keelbacked Treehoppers are bright green.  There is some good information on this Backyard Garden page.  The ants are attracted to the honeydew produced by the Treehopper nymphs.
