Their larvae are more commonly seen coated in a mass of froth – or cuckoo spit – on plant stems. By contrast, the nymphs of froghoppers do not jump and instead live a rather restricted life either underground, or on plant leaves, surrounding themselves with a protective froth which they make by blowing air into their urine.
