Cuckoo spit is produced in the same way as bubbles are blown in a children's game. Frog-hoppers suck plant sap and excess sugary fluid, honeydew, is voided.

The spit a five-year-old child produces in a single day, according to one estimate, could fill a 16-ounce soda cup.) Where we have salivary glands, the frog tongue itself produces spit.
