The butterfly shown in the photo is the popular Maniola Jurtina. It's a fairly common butterfly from the family Nymphalidae, found almost everywhere in the world, from the Iberian Peninsula to Japan.

But what's interesting here isn't its ubiquity, but its behavior. It simply enjoys contact with humans, or more precisely, with their sweat. Human sweat, which contains many mineral salts, is a very important part of its diet, in addition to other foods typical of butterflies.

I often encounter this species of butterfly during the summer, and it often lands on my skin and on objects touched by humans, where it can find a small amount of valuable substances.

The butterfly is small, with a wingspan of just over 50 mm. Females differ from females in wing coloration and size. Males are smaller, and the eyes on their wings are smaller than those of the larger females.

It is common in Europe. It primarily favors grassy glades, fields, and forest edges, where flowers and melliferous plants abound.

The butterfly overwinters as a caterpillar, feeding on grasses where it pupates. The butterflies emerge as early as June, and can even be seen in September, when the weather is warm.

My observations are from two periods and two different locations. The photos on flowers were taken in Silesian Park, while the others were taken in the Kraków-Częstochowa Upland.
