Aphid and an Ant

Lovely spot 박래원! Please consider adding this to the Symbiotic Relationships mission.

At the end of the abdomen of aphids have two siphons or cornicles, small erect dorsal appendages pointing backwards and upwards, by discharging honeydew which serves to bribe lashormigas. The ants protect many plants their parasites in exchange for receiving nectar from extrafloral nectaries usually located in the leaves. Aphids have developed in the evolution of a symbiotic relationship with ants, which not only tolerate them on plants, but protect them from specialized predators such as ladybugs or crisomelas, in exchange for the release of their siphons. Bees can also pick up that molasses, incorporating the composition of honey.
