Mud puddling butterflies

A great gathering of butterflies on a rocky slope in Mercantour NP

So many butterflies and so many species together! This was heaven for the butterfly buff! The spectacle of mud puddling butterflies is well known: they lick salt and minerals from the mud and rocks. A peculiarity is that only males gather in such numbers.

On holiday in Southern France last July, my wife and I walked along a rocky slope with a small stream when suddenly a cloud of butterflies rose into the air: we had literally stumbled into this mud puddling group. After maybe 30 seconds or so, they settled down again. I went onto my knees to look through the viewfinder and check the species. This was the colourful spectacle in front of my camera:A congregation of mud puddling butterflies in Mercantour NP

Then, you know there is only one option left: get down flat on your belly and start looking for the best shots. Like this Small Blue (Cupido minimus)…

After some 30 minutes my back and knees started to complain about the rocky ground, so I rose again (ouch!) but surely I did not complain at all…what a great day it had been for butterfly photography!
