Description: Let's rack up the magnification for a closer look at how the two wings meet. The hinge line seen from inside the open angle between the wings is the straightest feature of the whole specimen - it's clearly crystallographically controlled. In this view, the left wing is mostly reflecting the blueish light of the fill-in LED, highlighting the uneven surface texture (which was giving me a lot of trouble with my measurement attempts). FOV 6.2x9.1mm.
