Silver Studded Blue or an Idas Blue??

[Tinkerbell]

[pre][/pre]Found this butterfly whilst out with clients of Spanish Highs walking in the Poqueira Gorge on Sunday, turns out its either a Silver Studded Blue or an Idas Blue!! Only one way to tell the difference and that is by a looking at its ankle with a magnifying glass, hmmmm. The Idas Blue has a limited distribution in Southern Spain but is found in the Sierra Nevada.
