This is a millipede which I found crawling along on a scalding hot highway pavement in West Texas in August, 1999. I kept it alive on vegetable matter for a year or two, sitting outside my law office, in a cage. This is a posed picture, where I placed it on the cactus. I can't say that the millipede would have crawled around on a cactus, but I can't say it would not have either. I now have the millipede in a plastic case awaiting reattachment of a few of its many legs which broke off when someone roughly handled the plastic case.
