Butterflies in the Martletwy/Landshipping area

During a regular weekly butterfly transect at Martletwy/Landshipping area - commas, painted ladies, red admirals were all seen in reasonable numbers but no small tortoiseshells this weekend (one or two last weekend, but they still seem scarce). Three silver-washed fritillaries (similar numbers a week earlier) - they seem to be having a good summer. Large numbers of whites (all three common species) and the first clouded yellow of the summer noted.
