Bubbly Foam – Froghoppers

Have you seen the little bead of foam is on plants? and wonder what’s that?
It is a little bug called a Spittlebug and is the Nymph stage of a Froghopper.

Spittlebugs feed on watery sap from plants and then excrete bubbly foam to create a protective fortress around themselves. Later, they emerge as adult froghoppers.

Bubbly Foam on plant that usually I spotted it, but I don’t know what’s that and how it was formed.

The froghoppers, or the superfamily Cercopoidea, are a group of hemipteran insects in the suborder Auchenorrhyncha. Adults are capable of jumping many times their height and length, giving the group their common name, but they are best known for their plant-sucking nymphs which encase themselves in foam in springtime. Wikipedia

Luckily I spotted this view, I saw adult froghopper inside the bubbly foam, I think it’s ready to emerge.
