Adults are 9/16 to 10/16 inch long, black, and colorfully marked with
reddish-orange on the head, sides of the pronotum (part of the thorax),
and the wing covers. They have a Y-shaped head marking and two wide crossing
orange bands across the wings. They are common on milkweed plants. Milkweed
bugs eat the seeds of the milkweed. Their red or red-orange color is a
warning to would-be predators that they are very bad tasting food. So they
have few enemies. Spiders do prey on them, however.
