Caught this spider in the house this morning:
Eastern Parson Spider Herphyllus ecclesiasticus; body length 8 mm
Overwinter as adults, often in houses; "fast runner and difficult to catch"
Photographed under a glass-topped container, partial stacks with Zerene. Live spider that would tolerate only a limited number of flashes.
Top: Nikon 105mm MF Micro-Nikkor, reversed, maximum lens extension + bellows to give mag. x1 on Nikon D810 (full frame); lens set at f/5.6
2nd: at full lens extension and full bellows magnification was 2x but extreme tips of legs outside the frame
3rd: 105 lens not reversed + reversed Canon 50 mm 1.8 set at Infinity. Nikon lens at infinity and no bellows extension (however even when closed and mounted on camera there is a 75 mm extension)
Thus, with a reversed 50 mm lens on the 105 the minimum magnification on sensor is 3.6x
bottom: actual pixels from 3rd image.
I am very happy with the quality of the stacked lens setup.

Certainly looks like it has legs, but if you look at image 3 you can see similar 'structures' on both the right and left legs in the same positions; also the pedipalps seem to have them.
My guess is they are not mites, maybe some sensory structures

Lou: it is an old lens; came with a Canon FTQL (?) from the late 1960's. Left over from my 1st 'real' camera.
Canon Lens FL 1:1.8. Range to f/16. Small front diam , about 48mm.
I had to join together a 52 mm male ring to a 48 mm (?) male ring. The 52 screws into the Nikon, the other into the Canon

I was surprsied to see this spider here in February. It has been cold with lots of snow.
Checked my spider manual; 1st edition:
https://www.amazon.com/Spiders-North-Am ... th+america
and it seems spider hair may be "erect or recumbent; simple, serrate, feathery to plumose, or clavate to broad scales"
