Butterflies exhibit a remarkable diversity of feeding behaviours that extend far beyond simple nectar feeding. While floral nectar remains the principal food source for most adult butterflies, numerous species also exploit alternative nutrient resources such as tree sap, rotting fruits, carrion, dung, sweat, tears, and mineral-rich mud. These feeding strategies provide essential carbohydrates, amino acids, sodium, and other minerals necessary for survival, flight, reproduction, and ecological adaptation. The present review synthesizes current knowledge on butterfly feeding behaviour, puddling ecology, and the structure and function of siphoning mouthparts. Special emphasis is placed on mud-puddling behaviour, nutrient acquisition, feeding specialization, and environmental influences on feeding frequency.

The review also examines ecological and evolutionary aspects of butterfly nutrition, including reproductive advantages associated with sodium acquisition and the adaptive significance of feeding on unconventional substrates. Understanding butterfly feeding ecology is important not only for evolutionary biology and insect physiology but also for biodiversity conservation and ecosystem management. The review highlights the complexity of butterfly nutritional ecology and underscores the need for further studies on feeding adaptations under changing environmental conditions.
