Description

These spiders, called mirror or sequinned spiders, are all members of several different species of the genus Thwaitesia, which features spiders with reflective silvery patches on their abdomen. The scales look like solid pieces of mirror glued to the spider's back, but they can change size depending on how threatened the spider feels. The reflective scales are composed of reflective guanine, which these and other spiders use to give themselves colour.^[2]
