Willowsia nigromaculata
I agree in habitus images such as this one, Willowsia is easily confused with Entomobrya. Both belong to the family Entomobryidae.
With a microscope, the difference is seen easily: in Willowsia the body is covered with thin small translucent scales. In Entomobrya such scales are absent.

Willowsia nigromaculata is one of those typical domestic springtails. Often found in and around the house. Perfectly harmless, but could become annoying if they are with many...

Wow!
That's a nice close-up!

I'd take a gander & guess it to be a member of the genus Entomobrya.

Thanks Jonas...
There are many different kinds of these springtails and I find them everywhere. The 'spring' under the abdomen is something I would like to get a higher magnification image of. This image was with my 1:1 ratio Vivitar 105mm lens. It was cropped, but I can't remember the percentage.
