Graphocephala fennahi (rhododendron leafhopper) is a species of leafhopper native to the United States. Its common name derives from it feeding on the sap of rhododendrons.^[1] The species was introduced to Great Britain in the 1930s and continental Europe in the 1970s.^[2] There has been suggestion that the rhododendron leafhopper contributes to the spread of a rhododendron fungus (Pycnostysanus azaleae) through Europe.^[3]

Description[edit]

They are small as 8–10 mm and have 4 orange stripes down their elytrons. Their metamorphosis are incomplete, and those creatures are diurnal. Forewing colors are ranged from red to blue. Males are 7.4-8.8 mm long, and females are 8.2–9 mm long. They belong to the group "True bugs", very closely related to aphids and psyllids

Distribution[edit]

It is native to the mountains of southern Virginia, the western Carolinas, and northern Georgia.

Habitats[edit]

They are recorded in grassy lands, as well as in mixed hardwood forests, usually found in rhododendron areas.

Contribution[edit]

Rhododendron leafhoppers are usually vital food for ladybugs, spiders, and some parasitic wasps. They are afraid of Harmonia axyridis, the Harlequin Ladybird.

Seasonal occurrence[edit]

The Rhododendron leafhopper emerges from late spring and dies in November (timeline includes: May, June, July, August, September, October and November).
