Rhododendron Leafhopper Graphocephala fennahi
The Rhododendron Leafhopper is easy to identify even from just a picture. It originates from Northern America, but can now be found all over Europe as well, after having been introduced in the UK in 1935. It lives almost exclusively on Rhodondrendon. The animal is a good flyer, but it also jumps about enthusiastically. The nymph is hard to find, for it is almost transparant. The colour is a kind of milky green that blends in with the leaves of Rhododendron easily, as can be seen in the bottom pictures. It jumps about as eagerly as its parents do. The Rhododendron Leafhopper actually is not completely harmless, for it does transfer a Rhododendron disease. It is a milldew like fungus that causes the flower buds to die.
The Rhododendron Leafhopper is also known as the Rhododendron Cicada, the Green-and-scarlet Leafhopper and the Scarlet and Green Leafhopper.
