I knew it wasn't worth it...but I just had to try just to prove that I was right. The wind was blowing strongly, and although there was thick cloud cover and warm temperatures the moths did not arrive! Only 3 moths of 3 species. Flounced Chestnut, November Moth and Yellow-line Quaker, so all fairly nice moths, not many caught in the garden for each species. But still I was reminded of what a waste of electricity it was!
Some people just don't get it!!
