Mirror Spider - Thwaitesia sp I have been wanting to see this beautiful Spider after seeing other posts from Singapore and Australia and was taken by surprise to find one in Hong Kong.<br />
<br />
The species known from Australia is Thwaitesia argentiopunctata.<br />
<br />
This spider is very small in size, around 4-5 mm in size. They are called mirror or sequined spiders, which features reflective silvery patches on their abdomen. The scales look like solid pieces of mirror glued to the spider&rsquo;s back, but they can actually 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 color.

Mirror Spider - Thwaitesia sp

  1. Cool! I've fallen in love with this spider ever since seeing it on a blog from a Singapore macro photographer. Didn't know they are this small! Posted one year ago
    1. Yes, came to know of this Spider from the same guy, I believe :D
      Hope you get to see one in the future and yes, they are very small.

      1. Took me a year, but here we go :)

        Mirror spider - side view, Andasibe, Madagascar My first mirror spider! (Genus: Thwaitesia. I only once saw these online from a famous macro photographer from Singapore. They are much smaller than I expected and quite tricky to get entirely into focus. <br />
<br />
They are called mirror spiders due to the reflective plates on their abdomen. This one surely is in the genus Thwaitesia. Some candidates known to occur in Madagascar:<br />
<br />
- Thwaitesia argenteosquamata (Lenz, 1891) (Madagascar)<br />
- Thwaitesia pulcherrima Butler, 1882 (Madagascar)<br />
<br />
Not certain of the species yet, documentation is very limited.<br />
