These little metallic longhorn moths can be quite difficult to distinguish visually but, fortunately, they tend to appear at different times of the year:
- Adela cuprella: March, April, May
- Adela reaumurella: April, May
- Adela rufimitrella: May, June
- Nemophora cupriacella: July, August
See here for a female Adela reaumurella that I photographed back in May 2010.
