I found these aphids on a milkweed plant at my work. They were on many of the plants in the garden and are parasites to the milkweed, and some of the smaller milkweed plants were already dead and had few aphids remaining on them, possibly resulting from aphids depleting the resources of the plant and eating too much of it.

A large congregation of ants are seen eating away at an apple. When an ant finds food, she will leave a chemical trail to alert the rest of her colony. This is a sign of chemical signalling amongst eusocial insects.
