The torch can sometimes be more rewarding.

After the warm spring-like day yesterday I ran a couple of traps for a while after dusk in the woodland, but the temperature dropped off so quickly with clear skies that not much came to the traps. A walk round the woodland with the torch was far more rewarding with Dotted Border seen in abundance. Males perched on twigs were everywhere with a few seen paired up with females. During the hour and half I was there, 15 moths of 4 species came to the 2 traps (1 x actinic & 1 x UV LED). But by torchlight I counted at least 40 Dotted Border, all within 100 meters of the traps and not one came to the lights!

    Yes, I’ve noticed this myself Brian. I think that the moths are just active for a short time after dusk while it is still slightly warm hence why a few come in to light. Once it gets cold they just stop flying. I also think that Dotted border is not strongly drawn to mv light either.
