It is always worth taking a closer look at even the common butterflies when out and about.There is a chance that you may be fortunate enough to come across an unusual individual or more correctly an aberration.Most species it seems are prone to aberration and some forms of aberration are classified, but then again many are listed as unclassified.
For a comprehensive list and extensive information on recognized aberrations I would recommend a visit to the excellent website British Butterfly Aberrations.
