A genus of beetles, including the destructive corn rootworm, known for feeding on plant roots and leaves.
From Greek 'dia-' (through) and 'brotos' (eating/gnawing), literally 'eating through.' The genus name was coined in the 19th century to describe these voracious agricultural pests.
Diabrotica beetles cause over a billion dollars in crop damage annually in North America, making them one of agriculture's most costly enemies—yet farmers can't simply eliminate them because the beetles have evolved resistance to multiple pesticides in just decades.
