Still got the blues for you…

Four different blue butterflies on lavender

A week of hiking in the Morvan, Bourgogne, France resulted not only in pleasant memories of wine and croissants, but also in a colourful end of the butterfly season.

The week started off with overcast conditions and 18ºC. Not a single butterfly was flying around. But every day we hiked the temperature rose by 1 or 2 degrees, so we ended up hiking in 28ºC under clear blue skies. At our second B&B, the lavender bushes were blooming and at least fifty Blues were feasting on it. This pair of mating Common Blue (Polyommatus Icarus) was the highlight of the week:

I was so overwhelmed by the number of butterflies, all of them flying madly around and chasing after each other that it took me some time to discover that not all were Common Blues. Below is a Mazarine Blue (Cyaniris semiargus)

Then I spotted a butterfly resembling the female Common Blue, but it looked a little bit more chocolate brown and on closer inspection, it appeared to be an Adonis Blue (Polyommatus Bellargus).

Last but not least, a single Brown Argus (Aricia agestis) completed the spectacle.
