I found this moth earlier in the week on the camp site where I was staying. Took me a while to work out what it was as I hadn’t seen this species before.
It is a Mullein Wave which is a local species usually found on or near the coast – my campsite was within a kilometre of the sea. The caterpillars feed on wild marjoram, wood sage, horseshoe vetch, yarrow, mugwort and stonecrops. The adults have two generations per year, June to July and August to September.
