Pollinated flowers quickly transform into long slender seed pods. When matured these pods explode revealing the purest white silk attached to seeds, ready to catch the wind.

nymphs of the colorful milkweed bugThe reddish-orange color of the mature milkweed bug says, Don't eat me... I taste really bad!Milkweed bugs
(Oncopeltus fasciatus
Phylum: Arthropoda; Class: Insecta; Order: Hemiptera

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.
