What is the function of the cornicles projecting from the rear of the aphid abdomen?
Answer
Excreting defensive fluids
The cornicles, also formally referred to as siphunculi, are the two small tubes visibly projecting from the posterior end of the aphid's abdomen. These structures are specialized in function, serving as outlets through which the aphid can excrete defensive fluids when threatened or stressed. This mechanism is a crucial part of their defense strategy against predators or disturbances.
