The beet leafhopper (Eutettix Tenella Baker) has been found in four valleys situated in the Sierra Nevada Mountains. A natural breeding ground occurs in Honey Lake Valley at an altitude of about 4000 feet. The leafhoppers were found breeding in Red Stern Filaree (Erodium cicutarium) growing in a sagebrush area on the foothills. Early planting with reference to the spring and autumn dispersal of this insect is of no practical value in these valleys. There is no evidence to show that the adults migrate from the mountain valleys into the Sacramento Valley.
