Sorry, the pictures are really small. I should have used the larger size. They are posted in the Image Gallery for parasites in the first 3 pages I think.
The black ones are the ones that often have fibers spun around them. If I have red flannel sheets on the bed, then the fibers will include some red. The black ones also have the elongated body with a projection like thing from the middle.
Why would it glow with a black light?
