… but I didn’t do it. The blob of foam pictured hanging from the grass stem hides a spittlebug (Aphrophoridae). Spittlebugs are closely related to leafhoppers and feed by piercing plant walls and sucking out the sap. The foam is excreted by the insect and, mixed with air bubbles, creates a moist environment in which to live, and at the same time provides a place to hide from predators. Pictured is the spittlebug nymph that was hiding in the foam.
