Anomalous Heart and Dart? Surry UK (1 Viewer)

[Allen]

This can't be anything other than an odd Heart and Dart but I've never seen one with the 'heart' so elongated along the wing.

 

[Richard D]

Agreed on id and that is extreme elongation.

Looks like it's asymmetrical as well (most butterfly aberrations I've seen have been symmetrical, other than the obvious bilateral gynandromorphs, not sure about moths?). Obviously Heart and Dart show no obvious sexual difference so can't be that anyway.

 

[Allen]

No, symmetrical. Just not visible in the shot I attached. This one shows it.
