Description
The species is black in color, with orange legs and antennae.[3] Their size is quite small, about 1⁄16 inch (1.6 mm) long.[5]
Species lifecycle
The females lay eggs in soil, which has plants growing nearby. The eggs hatch in 7 to 14 days into larvae. While in their larval stage, their small, worm-like bodies are white. The larvae feed especially on plants' roots, causing serious damage. Then, they transform into pupae, and a week later, into adults.[5]
Pest
The species is known for causing damage to crops. The damaged plants include sorghum, soybeans, sweet corn, small grains, and some vegetables.[6] They feed on both sides of a leaf (upper and lower parts), including epidermis and the veins. They also transmit Stewart's wilt; by removing the leaf tissue from the plant, they open a wound which allows the disease to begin spreading from plant to plant. The disease organism is Pantoea stewartii.
