Behold, The Mirror Spider!

Thwaitesia:
Genus of spider that occurs worldwide in the tropics that feature reflective silvery patches on their abdomen.
Nicky Bay is a macro photographer from Singapore.  Bay credits the tropical climate as being a spectacular environment for his favorite subject to thrive in: Insects!

Bay was on one of his photo expeditions when he came across the Thwaitesia spider, aka, Mirror Spider.

He observed the arachnid for over an hour and watched its abdomen transform from silver speckles to mirror plated.

When Nicky first came across the spider, the mirror plates were relatively small and spaced out.

After an hour, the mirror almost covered the entire abdomen.

Nicky believe the mirror plates are a defense mechanism when the spider becomes agitated or threatened.
