What is the function of the salivary glands in a butterfly?

In butterflies, the salivary glands produce saliva that plays a crucial role in digestion and feeding. When butterflies feed on nectar, their saliva helps dissolve the sugars and nutrients in the liquid, making it easier for them to ingest. Additionally, the saliva can contain enzymes that aid in breaking down complex substances, facilitating nutrient absorption. Overall, the salivary glands are essential for the butterfly's feeding process and nutritional intake.
