At least four species of Empoasca occurring on truck crops in the United States have been designated under the name E.fabae and confused until recently. A study of the crops which they infest and the conditions under which they occur indicates that they cause economic damage and are distributed for the most part in different areas. E. fabae is a low altitude humid species occurring in the eastern U. S. E. filamenta is a high altitude arid species and occurs in the intermountain region of western U. S. E. abrupta and arida are low altitude arid species and occur on the Pacific Coast in abundance.
