Agonoscelis

Agonoscelis is a genus of shield bugs, in the monotypic tribe Agonoscelidini, that are native to the Afrotropics and Australia, but one species is established in the New World. Some species are minor or considerable pests.

They have five nymphal stages, and are 8 to 12 mm long as adults. They attack (or control) weeds and herbs including horehound, thyme, flax and cotton, or the developing seeds of sunflowers or cereals like millet or sorghum. They may swarm on a variety of other shrubs and trees, including coffee and cacao. The scent gland is located at the end of the abdomen.
