Despite an absolutely glorious day on the cliffs, we saw very little Lep activity, the one exception being Plutella xylostella, with 100+ seen at Horse Cliff. The cliff tops in this section are powdered white with Danish Scurvey-grass at this time of year (see photo below) and I'm guessing this is the main foodplant of what is presumably a home-bred population, although the dominant form was the pale-sandy type, which could suggest migrants – I don’t know? Sorry lots of speculation here! Has there been any migrant activity yet? Several Small Tortoiseshells, the only other species noted.
