I never cease to be amazed at the number and diversity of bugs in this region. I’m not sure what this critter’s normal job is but it seems to like my lettuce and it’s two hooked fingers on each leg / arm or whatever are impressive. 
This second photo shows baby’s hanging on to its belly – either that or beetle parasites. You can see two of them and when the original image is expanded they are in clear detail. I wonder what our closest common ancestor is to this critter.
