Eye Arrangement of a Hogna Wolf Spider

Unfortunately I still don't know the gender or species of this spider - but am confident that it's in the Hogna genus given the markings and eye arrangement.


Lycosid eyes may not be as clear or reflective as salticid eyes, but their arrangement is just as fascinating and wolf spiders supposedly have pretty good vision (although not nearly as applauded as the jumping spiders). A couple of times while photographing the spider seen above, his/her eyes would light up at certain angles just as cat eyes do in the dark - really on odd sight to see a spider with glowing eyes!


The image above was stacked from 5 photos using Zerene Stacker. The shots were taken at about 4:1 magnification with a vintage Pentax Takumar 28mm prime reversed to a set of extension tubes.
