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
as aphids, keeled treehoppers are tended by ants. So to control
bugs, instead of using insecticides, I take measures to deny ants
to the plants I want to protect. Yes, I do sacrifice some plants
provide keeled treehoppers for science class activities.
