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.
