I decided to trap on the beach last night. You need exactly the right conditions to do this and last night they were just so. Approaching the beach I noticed that the red and white Valerian flowers were alive with Silver Y and I counted at least 160 in a 30 yard stretch.
For some reason, not one of them came to the light traps, but I did record 45 other species including Shark (5), White Colon (2), Large Nutmeg (16), Bordered Sallow (4), Rosy Wave (3) and Fox Moth, – two females which is the first occasion I have had adults come to a light trap.
Micros included Anerastia lotella and Epinotia rubiginosana from the nearby pines.

I’ve had similar experiences with Silver Y. There have been times when I’ve seen large numbers along the coast during the day but after they don’t appear to make it inland in any numbers or turn up at light that frequently.
