Keeled Treehopper
Antianthe expansa

The keeled treehopper is generally considered a garden pest.  I most often find them on my tomato plants.  In large enough numbers, they severely damage, or even kill the plants.  Like aphids and other sucking bugs, keeled treehoppers produce a sweet fluid called honeydew which is attractive to ants.  In the same way as aphids, keeled treehoppers are tended by ants.  So to control the bugs, instead of using insecticides, I take measures to deny ants access to the plants I want to protect.  Yes, I do sacrifice some plants to provide keeled treehoppers for science class activities.
