I ran across two bugs today while hiking in Southwestern Utah. One light blue one and one green one. I have never seen these before and would like to know what they are.

Your blue beetle is a Desert Ironclad Beetle, Asbolus verrucosus, and since it is the end of the month and time for us to feature a new Bug of the Month for October, we have selected your submission. The color of the beetle is nicely contrasted by the red color of the rocks and substrate depicted in your photograph. There is a comment posted to BugGuide from a person who has raised Desert Ironclad Beetles in captivity and claims to have several individuals that lived more than ten years. The BirdAndHike Wildlife Around Las Vegas website states: “Desert Ironclad Beetles (Asbolus verrucosus) are medium-sized, fast moving beetles of the desert. These beetles eat plant debris on the desert floor, and apparently make good pets that live more than 10 years.” Another common name is Blue Death Feigning Beetle, and according to Bugs in Cyberspace, that name refers to: “their tendency to play dead when bothered, combined with a powder blue colored coating they excrete on themselves to protect them from the sun.” Your green insect is a Stink Bug in the family Pentatomidae.
