Dear Doesn’t Matter,
No one would ever accuse you of verbosity.  This is a Large Milkweed Bug, Oncopeltus fasciatus.  Both adults and immature wingless nymphs feed the seeds of milkweed by sucking on the juices.
According to BugGuide:  “Eggs are laid in milkweed seed pods or in crevices between pods. About 30 eggs are laid a day, and about 2,000 over a female’s lifespan, which lasts about a month during the summer. One or more generations per year. Adults overwinter.”

What's That Bug? does not endorse extermination

Orange and Black Bug

I’m growing Butterfly weed for the first time and there are these orange and black bug crawling on them that look a little bit like a box elder but only orange and black. (I see it’s on the cover of Kaufman field guide to insects of North America)

Hi Bill,
The Large Milkweed Bug, Oncopeltus fasciatus, will not harm your milkweed plants.  They feed on the juices of the seeds and sometimes take nectar.
