Spittlebug (nymph within spittle mass)

Gardens, fields, meadows, and areas with herbaceous plants, often found on grass, clover, and various weeds.

Plant sap (xylem fluid)

Spittlebugs produce a foamy substance, called spittle, to protect themselves from predators and desiccation. Nymphs live within this spittle mass, feeding on plant sap. Adults are free-living and can jump when disturbed.

Generally considered a minor pest in gardens, as their feeding can stunt plant growth but rarely causes significant damage. They are not harmful to humans or pets. In ecological terms, they are part of the food chain for birds and other insects.
