18. Hemolymph: More Than Just ‘Blood’
Insects’ hemolymph does much more than simply circulate nutrients.
It plays a crucial role in defending against parasites and infections, clotting to seal wounds, and even producing chemicals that deter predators.
For some species, hemolymph can be toxic or emit unpleasant odors as a warning.
This multifunctional fluid is a remarkable adaptation, supporting insect survival in ways that go far beyond traditional blood.
