Anatomical Atlas Of Flies

With a click on the desired magnification, and a simple drag of the mouse, all things become clear, and all parts have a name. I raged at the lack of adequate representation (simply put: I wanted to see more flies), but the three examples were well chosen to show the diversity of form in diptera. It's a great way to learn about fly anatomy, particularly wing venation, which is incredibly dry and somewhat confusing at times.

I'd post screencaps if I knew how.
