Zygogramma
''Zygogramma'' is a large genus of leaf beetles in the subfamily Chrysomelinae, which includes approximately 100 species. 13 species occur north of Mexico. Adults and larvae are herbivorous on various host plants. ''Zygogramma exclamationis'' is a pest species of sunflower crops in North America. At least two species have also been used as a form of biological pest control: ''Zygogramma bicolorata'' was introduced to India as a biocontrol agent for the weed ''Parthenium hysterophorus'', and ''Zygogramma suturalis'' was introduced to Russia as a control for '' Ambrosia artemisiifolia'' (common ragweed).

Zygogramma Exclamationis
''Zygogramma exclamationis'', commonly known as the sunflower beetle, is a species of leaf beetle belonging to the family Zygogramma. It is regarded as a pest of sunflower crops in North America. Description ''Z. exclamationis'' is a small leaf beetle, 6–12 mm in length, 2–4 mm wide, with a brown pronotum and yellow elytra marked with three, elongated brown stripes and a single, shorter, lateral stripe ending at the middle of the wing in a small dot that resembles an exclamation point. This arrangement bears similarities to the exclamation mark from where this species gets its Latin name. Adult beetles are morphological similar to the Colorado potato beetle, a pest of potato crops. The larvae are humpbacked in appearance, yellow-green in colour, and may measure in length at maturity.
