Tree Hopper – On Tomato
Q: Can you help me identify this insect found on my tomato plant, I think it is a buffalo leaf hopper. How to control it?
A: Good eye! Yes, it is one of dozens of species of tree hoppers and leaf hoppers that live in landscapes.
My friend Jule-Lynn Macie says it’s probably a keelbacked treehopper
They don’t do a lot of damage, so one option is to ignore them. But carbaryl (click for sources) or neem (click for sources) would control them if you spray when the nymphs are seen.
