List of symptoms / signs
Empoasca (Empoasca) fabae (Harris, 1841)
Empoasca fabae belongs to family Cicadellidae and genus Empoasca within order Hemiptera. Adults have pale to iridescent green bodies with 6 or 8 white spots on their pronotum. They are able to feed and reproduce on at least different plant species across twenty-six families. Empoasca fabae is a seasonal migration species.
