An important feature that separates E. excursaria from similar species is that the main dark line running across the hindwing is fairly straight but turns upward as it approaches the edge of the wing, and has a step at the end. This part of the line is not visible in live shots. The forewings need to be further open - which you can sometimes do by gently nudging the wing across with a stick maybe your finger. It depends how flighty the moth is. Another feature is the male's antennae. Your moth could be Ectropis bispinaria in which the male antennae have very short, fine pectinations. (E. excursaria also has fine short pectinations but they are a bit longer) I think I can see very short pectinations on your moth. I am not an anatomist but I think this is a male moth ? Your sightings are very important as you have raised them through so we are trying to get this right.

Hey @JenetC, there doesn't seem to be an image attached to this sighting, could you double check this? :)
