a look at Callophrys wings

These stunning green-patterned wings are those of Callophrys gryneus gryneus, the “Olive” Juniper Hairstreak. I was experimenting with some old Canon gear, a FD bellows and 35mm bellows lens, hoping to create a composite image of a butterfly’s wing. But, creating a clean series turns out to be impractical as the focus differed too much between shots. I instead focused on the patterns of green, white, black and brown on the wings, examining the melding of and contrast between the different colors.

The minute scales are arranged in such fine, detailed patterns which I always find it quite fascinating. But is not just the arrangement of these scales which catch my eye, rather the green color; it is not merely a smooth, consistent color across the scales, but instead glitters, as light reflecting off a rough surface. Though quite familiar with this iridescent, structure-based coloration in tropical butterflies, for whatever reason I had not quite expected to see it in this species.

Below a 100% crop of the image gives a better idea of the magnification achieved; the green color of the scales is also more evident.

After seeing the rough, glittering quality of the green scales I wanted to get a closer look. Using an old microscope, I focused on a single scale, first illuminating it from below and then from above. The difference was quite remarkable; lit from below the scale lost almost all of its vibrant green color, replaced with a mottled, muddy brown instead. But, lit from above, the startling green color reappeared, now glittering more than ever.

First two photos taken with a Canon 7D, FD to EOS adapter, Canon FD Auto bellows, 35mm macro lens, and 580 EX lens. Third image taken with a Canon 7D, homemade microscope adapter, and 580 EX flash; top image using transmitted light, bottom with reflected light.

  1. Wow! These photos are gorgeous! In that first shot, it almost looks like tapestry. And your close up photo of the scales are amazing! Great job!
