Image of Froghopper


These sap-sucking insects are about 7mm long, ranging from greenish-yellow to brownish yellow in colour. They have prominent eyes and strong back legs which allow them to ‘hop’ when disturbed.


A white frothy liquid (often called cuckoo spit) is secreted by the juveniles of the froghopper as they feed and can be seen on young stems and leaves of a range of plants in late spring and summer. The individual blobs of liquid contain a creamy white young nymph about 5mm long. The shoot tips of young plants may appear distorted with ‘torn’ leaves where insect has been feeding.
