Bordered Plant Bug, Largus californicus
These true bugs, ones with sucking mouth parts, live in the Sierras of California, especially in areas with lots of pine trees. These are striking looking fellows, with neon colored borders. They seem to like the patio or at least that’s where we see them most.
Home for these bugs is the U.S.A., they’re found throughout the country. They don’t seem to damage any plants, in fact, I’ve never seen one on a plant and in this area they’re called love bugs, because when they first appear in May, it’s mating season.
