Sharpshooter is a term used colloquially to refer to a highly diverse group of leafhoppers of the family Cicadellidae. Oncometopia nigricans (Hemiptera - Cicadellidae), pictured, is one of nearly 20,000 described species in that taxonomic family.
Like all true bugs, this species has piercing-sucking mouthparts, which are used to tap into and feed upon xylem or phloem (sap) tissue of plants. It also has large eyes and excellent visual acuity to avoid detection and capture by potential predators.
Oncometopia nigricans is an American species which as other ones, is considered a pest of several crops, because they can disperse relatively long distances, feed on a great variety of plants, and more importantly, they have the ability to vector (transmit) infectious pathogens from plant to plant.
