Wow! What a shot!
Why is it that white moths are often found resting on pink lady’s-slippers? Here’s one that I photographed last week in Abbo’s Alley. I knew where to find the plant. There — almost on cue — was its accompanying moth. Google “image white moth on pink lady’s-slipper” and you’ll see what I mean! Someone there has identified it as a “white slant-line.”
