Measuring along a wing and doubling and adding body width, I figure 72 holes, (43/cm) or 17mm if spread perpendicular.

Not sure if a species ID would be possible. In the future, an exact wingspan measurement can help.

Thanks, later I got a small ruler and measured more. that one only gave me the one shot and was gone.

You could "calibrate" your sheet, so you could always know size.

I can do that, but when the subject is at an angle like this, it seems it would require some trigonometry to figure out the size in the picture,. also I think printed wingspread measurements refer to fully spread specimens which would be larger.
Actually I see that the right wing is alighned with the sheet so I could get a pretty accurate measurement.

I use the measurement tool in PhotoShop. After measuring, just rotate perpendicular to the threads, and count.

 
I'm confused. I measured 43
I'm confused. I measured 43 threads /cm.
the length of the right wing from body to tip is 36 threads.

I assumed you meant ruler, by measurement tool but I see that it I enlarge the image, the ruler is going to get bigger, while if I shrink it, it gets to small to measure. Is there a measurement tool hidden somewhere?

 
Great tip, thanks!
