Spittlebugs

Philaenus spumarius

Meadow spittlebug

Its nymphs wrap themselves in frothy self-made spittle for protection, and adults leap many times their own body length once that cover is gone.

WhereGrassland, gardens and open ground
Size5 to 7 mm long
WhenMay to September

Adults are small, robust and oval, ranging from pale straw to dark mottled brown or nearly black, often with pale diagonal markings across the wing covers. The head is broad with bulging eyes, and the powerful hind legs give it a strong, sudden jump.

Nymphs feed on plant sap while hidden inside a mass of frothy secretion known as cuckoo spit, which shields them from predators and drying out until they moult into winged adults on an extremely wide range of host plants.
