This is a "Bordered Plant Bug"
Largus succinctus
The bordered plant bug does eat juicy plant bits, but general consensus seems to be that it won't do too much damage to the garden as long as it doesn't show up in huge numbers.
Interesting to me is that the bordered plant bug is so similar to both the box elder bug (Boisea trivittata) and the red shouldered bug (Jadera haematoloma), both of which I came across in my research on the goldenrain tree (Koelreuteria paniculata). Red shouldered bugs in particular are so attracted to the goldenrain tree that they are sometimes referred to as goldenrain tree bugs. They are also commonly despised by people who have these unique and beautiful trees near their homes. It seems the biggest problem with all of these black and red buggies is their desire to overwinter inside your house. Then they crap all over your stuff and ... well, you get the idea.
So, this bug is more of a pest than a pal, but there are way worse bugs to worry about. I'm going to file this one under Nuisance: Kill on sight but don't begrudge the ones that get away ... and don't invite them in for tea.
