This colorful crab spider is one of the flower-inhabiting members of the family Thomisidae. Six of the eight eyes are seen roughly straight on while the two remaining members are only seen by their lenses. The eyes are on what arachnologists call prominent pale tubercles.

Walt,
Here's a part of something I once posted:
Those two eyes were interesting. No flash was used. While taking the photos it was apparent that the spider could "rotate" or ""move" something under the surface that made the eye appear either red, black, or partially red/black when viewed from the same position.
I can't say either, but I have noticed something when photographing these "in the field".Can't say if the red eyes are different
