When the native evening primrose (Oenothera biennis) blooms, you know it is time to look for the gorgeous evening primrose moth. Here, two are huddled inside the flowerhead. This is the way you almost always see these moths during the day, but occasionally one might be perched mostly outside the flower and then you'll see that they have lovely big green eyes and what looks like a white fur cape. Check out a couple of other photos of this moth: http://www.pbase.com/fwg/image/148381002 and http://www.pbase.com/fwg/image/104979563
