Name the pest that is 1/8 inch long, green, and wedge-shaped.

Green peach aphid
Potato leafhopper
Spider mite
Whitefly

The correct answer is: Potato leafhopper

The potato leafhopper is accurately described as being approximately 1/8 inch long, green in color, and wedge-shaped. This pest is known for its distinctive appearance and can cause significant damage to crops, particularly alfalfa and various vegetables. The wedge shape is characteristic of adult leafhoppers, making them easier to identify among other pests. In many cases, distinguishing pests by their size and shape is crucial for implementing appropriate management strategies. Understanding the physical traits of the potato leafhopper helps in recognizing it during field scouting, enabling prompt action to minimize crop damage. This particular identification is essential, as the potato leafhopper can transmit plant diseases and lead to yield losses, especially in susceptible crops.
