One of the garden boxes has a mishmash of plants. One volunteer tomato plant, six marigolds, one chrysanthemum, two mints, a few chives, a couple of purple basils and one struggling rose cutting are all growing there. In the midst of all those leaves, a red dot scampered. Aha! A ladybug had found the mother lode of aphids and was a happy camper! I watched as the ladybug raced around the leaves in search of aphids. It would then chow down on its prey before starting anew. The race was on!
On closer inspection, there were many ants on the same plants. At first, I assumed the ladybug was merely trying to outrun the ants but it kept coming back to run atop them again and again. Then I realized that the symbiotic relationship between the ants and aphids was how the ladybug found its meal. Ants literally "farm" aphids. As the aphids suck the juices out of my plants, they excrete "honeydew" which the ants love. The nectar rich resource is food for the ants. In return, the ants protect the aphids. (There have been cases known where ants will tote aphids with them if they have to move their nests.) The ladybug, on the other hand, dines upon the aphids, themselves.
Usually, the ants and ladybugs tolerate each other and pretty much ignore one another. Neither are predators to the other. They both happen to be interested in the third insect..the aphid. Personally, I would rather have the ladybugs than either the ants or aphids! Chow down, Ladybug!
