Chalcoscirtus diminutus is a species of jumping spider in the family Salticidae. It is found in the United States.
Wikipedia has more photos. Apparently it has no common name.
There’s a cute insta where someone has silly conversations with their pet jumping spider, and then they made a reel for one of the spiders that died and I got all choked up and I’m sure I’m fine.
