Immature Large Milkweed Bugs

Plump Black and orange bugs
I found several of these bugs in a flower garden. It was the 4th week of September around 4pm. Can you tell me what they are? If they are beneficial, I don’t want to destroy them.

Hi Cathy,
These are immature nymphs of the Large Milkweed Bug, which we just identified for you.  Like other Hemipterans, they have sucking mouthparts, and they feed on juices from the seeds and seed pods of milkweed and dogbane.  We have never located any information that this is a problematic species in the garden.
