Adult large milkweed bug showing full coloration and wing development, two older nymphs showing partial wing development, and an orange, very young nymph, partially obscured by the adult.
Milkweed and goldenrod are now at their peak. Adults and nymphs are abundant, with feeding aggregations observable throughout fields in east central IL.
These insects feed on milkweed seeds, incorporating plant toxins into their own tissues and advertising their bitter taste through their obvious markings and coloration.
