Giant Leaf-footed Bug

Acanthocephala declivis

Also known as Broad-Necked Leaf-Footed Bug

Giant leaf-footed bugs navigate forest canopies and suburban gardens across southern North America, using long piercing mouthparts to drink nutrient-rich sap from woody plants and fruit. Broadly expanded, wing-like pronotal shoulders give adults a distinct broad-shouldered silhouette that easily distinguishes them from close relatives. When threatened, these robust insects release a pungent defensive fluid from thoracic glands to deter hungry predators.

Responsible observation
  • Spotting: Scan tree trunks, thickets, and garden foliage on warm sunny afternoons.
  • Disturbance: Maintain a short distance to prevent the bug from dropping off branches or flying.
  • Protection: Avoid squeezing or picking up adults directly to prevent defensive stinks or beak pokes.
