Crossing the Chaco region of Argentina on our way to Salta is rather hot and monotonous as we are dealing with a rather straight road that goes on for a few hundred kilometres across this semi-tropical area of the country.

While driving we were talking about the news and pictures received from our daughter and our friend Lola from Rome where we learnt that snow had fallen a few days back. We agreed that we were lucky to be mostly in warm climates, away from winters most of the time!

We were in the middle of the discussion when we passed an area where, maybe because of the subject we were discussing, it was snowing!

Or so it seemed to us for a few seconds until we realized that we were crossing an area populated by millions of white butterflies known locally as “pilpintos”.

Apparently, these butterflies appear after the rains and live rather short lives and mainly stopped in the rain puddles to recharge water and salts.

We were happy to realize our error and continue on our way to our summer South American hiding spot!
