Leaf-footed Bug – Nymphs
Q: I noticed a clump of very bright red insects on the underside of a sage leaf. They seem to be too big to be spider mites and they seem too bright to be fire ants. Do you know what they are?
A: I believe they are the nymphs of the leaf-footed bug. This insect feeds on tomatoes, squash and okra in your garden.
The adults lay eggs in fall and the eggs hatch in mid-spring.
If you see an adult, don’t handle it. The sharp mouth part it uses to suck plant juice can pierce your skin and it will hurt!
