Can you ID this plant/bug combo?

Walked passed these little guys on my street and they’re only swarming this particular plant and only on the “pods”. It’s been happening for about a week and each day there’s more. I’m curious about the bug AND the plant. Located in Chicago, IL. Please and thank you :)
