Little identification help please?

Edit: Halictus scabiosae, identified through observations.be with 99% certainty.

What am I looking at? Except a very industrious little worker?

How do I go about figuring it out? Is there some reliable site that would allow me to refine by stripes and such? Thanks.

This is Wallonia, Belgium. I got a new camera, which allows me to get much more detailed entirely useless pictures! I was one with the bees for an entire hour, came home with 500 pictures, and this is the only photo I got of this one. The stripe pattern struck me, with the very sharp lines, but I have no head, no thorax, no nothing...
