Aberrations

One of my guests on the butterfly tour last month brought this Chalkhill Blue butterfly to my attention. It’s unusually coloured. It’s an aberration, a freak, a variation that nature sometimes throws into the pot. I was curious what the Butterfly County recorder, Andy Brazil,  would make of it. Here’s what he said:

Chalkhill’s have historically had a lot of variations recorded, but we’ve not had any from Norfolk before.

There’s a similar aberration here http://www.ukbutterflies.co.uk/phpBB/gallery/image_page.php?album_id=271&image_id=11243 named as post-obsoleta, but this female also has a paler, washed-out ground colour of ab pallidulla. I’ve looked through this list http://www.ukbutterflies.co.uk/aberrations.php?species=coridon but nothing quite matches the combination. So I’d say it was ab. post-obsoleta ab.pallidulla so two aberrations on the same insect!

So there you go. Another first for Norfolk!

Being Blown Away

We’ve had some wonderful sightings of Chalkhill Blue Butterflies on our Norfolk Safaris of late. Thousands of the tiny blue creatures hatched on turf covered chalk to create a moving carpet of butterflies that blew us away! Undoubtedly one of the best wildlife spectacles that understandable ‘choked up’ some of our guests so beautiful was the display.
