Asclepias asperula or Antelope Horns Milkweed. Its the host plant for caterpillars.

Phoenix, you are awesome! What a wealth of plant info. Thank you for identifying my 2 mystery plants today.

I am not sure about the bug's name, but they birth inside the cracked seedpods. I do not see any damage from these bugs when the age. They seem to disappear.

That explains why the bugs were only on the older damaged pod. No bugs on the intact pod. Interesting! Thank you, wantonamara.

Monarch butterflies

The monarch caterpillars are on there also but not in the numbers that theses bugs are. I was just out collecting seed for someone and I was up close and had ti chase the little guys out more than once. The pods crack open and then hang for a bit before they crack open further and the seeds fly in the wind. I have a lot of these in my field. They are one of my most favorite flower.

I forgot to mention that the plant disappears as the summer progresses. orange aphids also like it

I'm pretty sure those are Black and Orange Milkweed Bugs and the following is part of an article I kept when I learned of these bugs years ago

The Monarch Butterfly Caterpillar has a symbiotic relationship with these bugs. No self-respecting bird would eat the Milkweed Bugs, so the caterpillar remains relatively safe until it becomes a butterfly, a butterfly which, because it eats milkweed, is distasteful to birds.
