July Iridescence 1


August 10, 2015

Until the last couple of weeks it has rained more days than not in northern Ohio this summer. Still I’ve been able to catch some evidence of my favorite iron bacterium, Leptothrix discophora. Here are three views of a patch that somehow survived the downpours.

    • Thanks, Ken. This patch was about two or two and a half feet long, so about six inches across in the widest part.

    • Thanks, Barry. I just love this stuff. There’s a lot of information about the iron bacteria (and more photographs) at scienceandartpress.com.

  5. Thank you, Joshi. I love this iridescent film so much that I find it difficult to know when I’ve made a photograph that will appeal to others.

  6. I only wish I could see a patch that big! Usually I only find small spots (less than 6-8 inches or so) and sometimes in very hard to reach areas of a pond.

    • I more often see only small patches of Leptothrix discophora, too. But July and October are the best months to see them large. The warm weather helps, as does the absence of rain, which disperses them or washes them downstream. I was able to wade across the river July 31 and found some patches about four feet across. The larger patches aren’t always the most beautiful, though.
