Spittlebug


Spittlebugs are interesting insects, the nymph produces a white frothy substance on stems and leaves which looks just like spittle! Hidden underneath that froth is the juvenile busily sucking out sap from the plant. This froth serves to protect the youngster from adverse weather conditions, reduce the risk of dehydration and to deter parasites and predator attack.



The insect adult (pictured above) has a narrow curved horn on the front of the head. It is brown and can be found here on the Coffs Coast. Even though they are sap suckers they rarely cause significant damage.

If they offend you they can be hosed off or the affected part of the plant can be pruned off. They usually take up residence in natives including wattles, gum trees and casuarinas.
