Ever wondered what the foamy like spittal in the grass is this time of year? Commonly known as Cuckoo Spit this froth serves a number of purposes. It hides a tiny Froghopper nymph from the view of predators and parasites, it insulates against heat and cold, thus providing thermal and also moisture control. Without the froth the insect would quickly dry up. The nymphs pierce plants and suck sap causing damage, and much of the excess filtered fluids go into the production of the froth, which has an acrid taste, deterring predators. Thanks as usual to the mighty Wikipedia!

However there is no explanation that I can find as to where Cuckoos feature!  If anyone knows please post a comment!
