My word. That's a handy illustration. Reinoud, the best I can manage is the attached (enhanced, seriously cropped). None of my images was particularly good for this species; I ran off a few from a distance using whatever settings the camera was at for whatever hapless beast I'd snapped earlier, but as I drew close and started to fumble with the camera to increase lighting and aperture it took off, so all I have are poor. Thank you again.
