This mantid appeared to be guarding the lock the other night. I took some pictures and then picked up the lock with it still on. It crawled up my arm but must not have liked the movements, so it jumped to the ground.
I thought the coloration was very interesting. Brown being a better camouflage than green in a desert setting for one, but the markings on it aren't plain as some are. Must be useful on a specfic type of bark or leaf litter.
