Dont spit on my bug

At the Hayfields there is this spit like substance on the leaves.We identified that this belongs to the spittle bug. The bug we saw is a juvenile form of a spittle bug. The adult version is the image on the left. Nymphs,  create the spittle while feeding on plant sap. Adult bugs feed on plant sap too, but they create no spit. Adults are often called froghoppers. They exhibit the astounding ability to leap great distances in a single bound.
