There is a technical term for spit, it is saliva flob. Here are some facts:Flob's production (in salivary flob glands) is stimulated by the presence, the smell or even the idea of food. Flob contains a lubricant (mucin) and in some animals it contains an enzyme to start the digestion of starch - ptyalin or amylase. Insect flob contains other digestive enzymes and blood sucking craeture's flob has an anti-coagulant in it. Plants don't make flob but some look as if they do - that's called 'cuckoo spit' and is made by an insect of some sort.
Llama "spit" is actually regurgitation, so I suppose it should be described as llama projectile vomit.
FYI - Cuckoo FlobLatin name: Philaenus spumariusSize: The adult insects are between 4 and 12mms, depending on the species.Distribution: Commonly found throughout the UK.Months seen: April to June.Habitat: Woodland edges and grassland.Food: Plant sap, extracted from the leaves and stems.Special features: Many people are familiar with the frothy mass, commonly known as "cuckoo spit", which is seen on plants in spring and early summer.The froth is created to help protect the developing nymphs of froghoppers. The nymphs drink more plant sap than they need for growth and health. The undigested excess is then blown out of the back end, producing the froth. The froth hides them from predators.The name "froghopper" comes from the appearance of the insect when viewed from above, which is quite frog-like. The similarity is enhanced by the insects ability to jump incredible distances.(...sorry, you cannot view external links. To see them, please
