Chalkhill Blue aberration

[millerd]

There are probably more listed aberrations for this species than any other - the Victorians were a bit obsessive about the Chalkhill Blue, and there are a myriad of subtle differences described.

Nevertheless, this distinctly different individual turned up at Box Hill (Dukes) this afternoon. With such strong sunshine hardly any of the species were opening up at all, but as luck would have it this particular male bucked the trend and showed off a bit. The underside was not strikingly unusual...

...but the top certainly was.

A normal ChB male for comparison.

Does anyone recognise it and have a name to hand?

Cheers,

Dave

I don't know how you do it Dave! I don't have a name for it - tho' I am sure someone will. It is very pretty nevertheless

What an absolute Cracker Dave ! you,ve really got your eye in for abberations this year .......................Nice One !!
How about AB;Fowleri or Punctata- Margino
Just a thought . Regards Allan.W.

Complete luck, Pauline! It just appeared in front of me and opened up... Yes, an attractive variation too.

Thank you, and for your thoughts on what it might be called, Allan - looking at the "British Butterfly Aberrations" site, ab. fowleri looks closest. However, like a lot of abs, it's nearly, but not quite like the pinned example.

Cheers,

Dave

I reckon a combination of fowleri + ultramelaina. Very eyecatching whatever it's classified as
