Silver Washed Frits 2017

Early July 2017.  A good time to checkout the silver washed fritillaries at Holt Country Park Norfolk.

 

 

It is only in recent years this magnificent butterfly has colonised the county.  They are doing really well and can be found in a few woods, the best being Holt in my view.  Going early means they are in the best condition, our visit was in late afternoon and we were lucky they decided to nectar so we had cracking views down to a few inches!

Two special sightings the first a mating pair.  The male however seemed more interested in feeding.

The other was my first sighting of two females of the rare form valezina.

 

 

This beautiful blue colouration only occurs in a small percentage of  females.  It is mainly only known in the south of the Country in the large colonies of Dorset & Wiltshire for example.  I was aware they had been reported at Holt so it was a thrill to see not one but two, and so close I had to step back to focus!

I noticed the valezinas kept in the shadier areas and have read that this is possibly because they cannot regulate their body temperature as well as the more normally coloured silver washed frits.  It did make for some nice images even if it meant I had to have a high film speed and slow shutter speed.
