A large seed bug, Dieuches armatipes Walker, was recorded in several Florida counties (Alachua, Levy, Polk, Highlands, St. Lucie, Henry, and Palm Beach). Native to Africa, D. armatipes feeds on peanuts during the harvesting process by piercing the pod and feeding on the oils, thereby causing the seed to shrivel and reducing germination rates. This species also feeds on a large variety of ground seeds, and has been observed feeding on seeds of weed species.
