<p>You may have noticed by now that the eyes of jumping spiders can be several colors, but I have noticed that female Maevia iclemens are often <i>exceptionally</i> vivid. With their beautiful deep blue anterior median eyes displaying the occasional moving wash of red due to the internal movement of the spider's retina, they are truly remarkable. 
</p><p>I found this little (~5mm) female Maevia inclemens in a light fixture on my back porch, and upon noticing that she was going to be quite a cooperative subject, I ran back inside and grabbed my macro bellows. I have no way of judging exactly what magnification the photo above was taken at, but I am confident it was taken past 5:1 with th 28mm reversed to the bellows. I spent a little bit watching her through the viewfinder as I could actually see that red haze move about behind those lenses! It's absolutely remarkable to see these movements - I'll have to try to get a video of it sometime soon.
</p><p>The photo above is a focus stack from 4 photos taken at f/8 and cropped pretty significantly. I only got 9 photos of this spider before my good luck turned and she hopped away and I lost her. I thought I was getting better at finding escapees, but her flee was successful - I never found her.
