Aphrophora major is a large froghopper, somewhat larger and broader than Aphrophora alni. Adults are 10 - 12mm long and can typically be seen between August and October.
As is typical with froghoppers, they have two stout spines on the outer edge of the hind tibia, as well as several smaller spines at the tip.
The Aphrophora genus can be recognised by the keel running down the midline of the head and pronotum, and the particular species by the colour pattern.
Aphrophora major forewings are covered with fine hairs and are uniformly brownish with black puncturation. There are sometimes irregular darker areas.
