Great job, guys & girls & others (just trying to cover all bases here :))

The color spots showing which seta is which is very incluttered - an almost perfect illustration for the purpose. It would be perfect of you would have the names directly in the legend on the right side. Having to look up the number adds an unnecessary step.

Alternative names for some setae: first postsutural supra-alar -> prealar seta (logical - as Tony's illustration shows, it is in front of the wing base. The strength (or absence) of this seta is frequently used as a key character in Muscidae.
