Saturday the 10th, a group of us took a walk at Sheri Capehart Nature Preserve to find moths at sunset. They are very special moths that pollinate and in turn are fed by the Glen Rose Yuccas that live there. It’s a great example of biological mutualism, and it’s the subject of my most recent “Letter to Nature Folks.”

I hope you’ll visit the page with “letters” to you and download that May issue of Letters to Nature Folks – the one marked as “Yuccas and Yucca Moths.” And if it sounds like a good walk (it was a very good walk), thank John and Grace Darling for leading it and telling us the story of how the yuccas and moths completely depend on each other. And thank the Friends of Sheri Capehart Nature Preserve for offering this and other great activities. (Disclosure: I’m on the board of that Friends group, but I’m not the one to thank for the walk.)
