👉 Wing fluid, also known as wing plasma or wing hemolymph, is a complex fluid found in the wings of insects, playing a crucial role in their flight dynamics and overall physiology. It serves as a medium for nutrient transport, waste removal, and immune response within the insect's body. Notably, wing fluid contains proteins and enzymes that contribute to the structural integrity of the wings and help maintain their flexibility during flight. Additionally, it plays a role in regulating temperature and hydration, ensuring the wings remain functional under varying environmental conditions. This multifunctional fluid is essential for sustaining the insect's ability to fly efficiently and adapt to its surroundings.
