NOT NATIVE
Red Bug is native to the Mediterranean area. It feeds on the seeds of plants, mainly plants that completely die out at the end of the year and can only be grown from seeds, which makes Red Bug a threat. Red Bug was noted by BugGuide as being first reported in California in 2009.

They are considered invasive, because of lack of predators. People in California report that even their chickens stay away from them. Harvester ants seem to be their main foe.
