I'm not sure why this group of moths are called Quakers, the don't seem to quake that much to me. The bottom one is the Common Quaker, I caught 21 last night, and I caught one each of the Small Quaker on the left and the Powdered Quaker top right. As the days and nights warm up the variety of moths will increase and the species will change, although this year there is already evidence that species of both butterflies and moths are emerging earlier than usual.
A bit more striking, this is the Angle Shades, normally on the wing from May but can be encountered throughout the year. This was my first for 2007.
