Water, Rove, Scarab, Long-horned, Leaf, and Snout Beetles
is the largest and most diverse suborder of , comprising approximately 90% of all described beetle . The name derives from Greek 'poly-' (many) and 'phagein' (to eat), reflecting the group's varied feeding habits. The suborder is defined by two morphological traits: the hind does not divide the first and second abdominal , and the notopleural is absent. Polyphaga contains 144 across 16 superfamilies and five main infraorders.
