Silver Studded Blues at Prees Heath 10 th /17 th June

It is now 10 th  June, the Cornonavirus lockdown restrictions have been partially lifted so i can now drive any distance for leisure/exercise  purposes.  Except Wales and Scotland.  so still cant go into Snowdonia .  But the Silver Studded Blue butterflies  should be emerging now at Prees Heath in Shroposhire . So with very light winds and a cloudy forecast i have driven down to see if i can photograph a few.
These butterflies quite often emerge in huge numbers, and unlike most species don't actually move very far so they are always to be seen flying low around the Bell Heather

It didnt take long to find them ,  they are roosting in the heather,   all males which are blue underwing, whereas the females are brown.  They always emerge first.

It is an old airfield , the Bell Heather has been seeded on the old runways over recent years to increase the habitat for these fairly rare butterfly.

 I have found a nice fresh male , probably emerged in the last 24 hours ,  placed it on a nice colorful dead  heather stem .  held in a small clamp.  i can now lie down low to shoot with a nice clean background .

                                               Beautiful colours of the dead heather stems.

All the butterflies seen so far have been males ,  but after half hour of searching i have found a newly emerged female still on the heather but low down out of sight , it is cloudy and fairly cool so the males are not flying around looking for the females yet.

It is now just gone 10 am , and the sun is breaking through the clouds and the butterflies are becoming more active.   opening there wings to the sun .

                                                               One last image of a male .

A week later on the 17 th i have come back to see if a bigger emergence has taken place , we have had quite a few thunderstorms over the last couple of days so that may have had an impact on them.  It is a bit breezy today, but much warmer than last week when i arrive and immediately i notice how much more active they are, the numbers have increased dramatically also with plenty of females spotted already , considering i only found about 6 last week.   Unfortunately most of the males are roosting but take flight as soon as i get close !

A Small Heath , there are plenty of these flying around and this one stayed motionless to allow a 4 frame focus stack.   

                           A picture clearly showing the difference between male and female.

         One of dozens of females that i have found , all the males seem to be very worn already with scales missing all over the wings.

It is just too warm now , they are all too flighty but i have just shot this beautiful female on a heather flower to finish with.   I have not found a single butterfly emerging with the ants which is disappointing.
