I live in Phoenix Az. I do have a front yard garden of some herbs, tomatoes, and artichokes. I don’t think the bugs are there for the garden. They spread out through the dirt portion of the yard and have trails (4-5 trails that they’re following) all the way past the garden and into the backyard.
I found false cinch bugs have similar body shape, but not the markings. Our neighbor is redoing his entire house, so I’m wondering if that’s where they came from?

Dear Morgan,
Last spring we posted an image of similar looking nymphs, and at that time we wrote:  “These are immature True Bugs, and nymphs can be very difficult to identify.  …  we suspect you may also have Dirt Colored Seed Bugs in the family Rhyparochromidae.”  When we received images of the adults, we tentatively identified them as California False Chinch Bugs,
Xyonysius californicus, but alas BugGuide does not have any young nymph images.

Thank you! That gives me enough info so I don’t have to worry about them. I really appreciate he quick reply.
