Yes, they can bite. Not a big deal, but it can be surprising! If you just let them run across your hand without actually getting hold of them, they are less likely to try and bite.
Make sure to use a camera with a macro setting. Our Kodak Zi8 has a good setting for this. Also: when the mantid is feeding, it is distracted, and more likely to let you get close to it!
Thanks! Our student worker Caitlin Stamper shot this video.
