There is a good explanation here, Peter.

A very interesting photo.

Thank you for the link Amelia it's very interesting the water is in the old lime workings at Calk Abbey, I had gone there to see the orchids

Just amazing to see; nicely captured Peter.

Today Geo found a meeting of swallowtails, and last year I found one of Blue Butterflies !
There is something in the ground that is attractive to them !! You also have your nice meeting today, while I was playing petanque with some friends lol !!! Have a nice week to come, Peter !

Did you upload this a few weeks ago! If not it must have been someone else with an uncannily similar shot!
Anyway, good to see again !

Hi Andy I only took it yesterday if you read the link Amelia put it explains what they are doing

My mistake! Yes I read the helpful link. It's obviously a common thing so it was unsurprising that someone else posted a very similar shot a while back!

Remarkable capture!

That's a nice collective name Peter. I have never seen so many together! Well spotted and taken. Have a nice new week.

Nice pic. They're probably attracted to the dampness--I've seen butterflies on mud pretty commonly.

Absolutely stunning! ¨*•.¸¸♫♪
