tenax

The rows of hairs down the eye, visible in the first picture, are unique to tenax.

actual hairs on the eye?

So when a hoverfly is described as having 'bare eyes', or face, this is a good contrasting example..?

Eyes

Eye hairs are sometimes very long and evenly distributed, sometimes really sparse and very hard to see (lens or microscope needed). This is the only species I know of where there are rows of longer hairs down the eye, though, which can be seen with the naked eye.
