Cornicles are tubes that project from the abdomen of an aphid. There are usualy a single pair of cornicles with one on each side of the abdomen. The cornicles are used to emit pheromones or defensive secretions.
It is often incorrectly believed that honeydew is secreted from the cornicles. Honeydew is actually excreted by the aphid from the rectum.
