Black Willow Leaves Curling 2624

From February 7, 2007, here’s a close and abstract look at two curling leaves of a black willow, Salix nigra. I don’t know what caused all those the dark spots.

  3. “A number of diseases plaguing willows are transmitted by insects. Willow blight, Pollaccia saliciperda, is transmitted by borers of which Salix species are the only known hosts (Pitcher and McKnight, 1990). Symptoms are dead leaves and shoots due to fungal infection with striking black spots on the leaves shoot tips blackened and shaped like hooks. The damage can be so extensive that entire tree appears to have been denuded by feeding insects (Stihl, 2010)”

    • Thanks for that information, Elisa. I had no idea what the spots might be. harmful as the spots may be to the willow, I still like the spots visually. The botanical species name saliciperda means ‘causing loss to willows.’

      • Thank you! I wasn’t sure, I just found it and shared it with you. I could hope that I am wrong!

  4. Steven—icy cold here in Austin area today—-hope you are enjoying better weather wherever!!

    A comment, not on today’s photo, but the series in Spring 2015 issue of WILDFLOWER magazine. They are all stunning images, especially the wasp with what appears to be pollen on it’s back pictured on the butterfly weed.

    Just wondering—were you lucky enough to capture all those images on one photo shoot, or were they compiled over time?

    • Hi, Esther. I’d be lucky indeed if I could get that many good pictures of insects in a single photo session. The photographs are from various times and places.
      Here in New Zealand the temperature is pleasant, quite a contrast from what you say is happening in Austin. I don’t mind missing the cold at all.

      • Oh—lucky you!!! What a fantastic country!! Visited there 20 years ago exactly this same time of year.—so nice to be enjoying summer while those of us here in the states are shivering.

        Don’t miss Milford Sound!

        • Unfortunately we don’t have enough time to make it that far south, but we’re seeing plenty of good things.

  6. Maybe the leaves have some compound that forms a crusty deposit as they dry.
