Thank you Christine.
She was most of the time laying flat out in the foliage going for bugs. The foliage is fairly thick for about a foot deep then it thins for the next foot of height. It's amazing how she could disappear so well. If I didn't know she was there, she just looked like a innocuous white spot until she lifted up & moved to a new area. My dh with eagle eyes was the one to spot her & alert me otherwise I'm sure I would never have known.
