Two confusing butterflies

My first guess when I see a tortoiseshell butterfly is the Painted Lady (Vanessa cardui). It is the most widespread of all butterflies, and found on all continents except Antractica. But when you are in the middle heights of the Himalayas, between a thousand and three thousand meters above the sea, you could be wrong. Think instead of the Indian tortoiseshell (Aglais caschmiriensis, featured photo), and the less common small or mountain tortoiseshell (Aglais urticae). I’d learnt this on a walk at a height of 3.1 kilometers, when I realized that I need to look at little details on the hind wings to differentiate between them. Now, on a walk in Binsar at 2.4 kilometers of height, I remembered the lesson again.

When I stopped to carefully photograph every butterfly on the trail, The Family decided to walk on at a steady pace. But I was happy to make a record of the relative numbers of the different tortoiseshells I saw. No painted ladies. Many Indian tortoiseshells. And one solitary sighting of the mountain tortoiseshells (above, resting on a bed of dry oak leaves). I count myself lucky at that. It had been a very warm and dry winter, and these butterflies are very sensitive to warm seasons. I’ll have to learn to tell the difference between these butterflies by looking at their hind wings. If I can do that, then I can identify them as I keep pace with The Family on such walks.

I travel on work. When that gets too tiring then I relax by travelling for holidays. The holidays are pretty hectic, so I need to unwind by getting back home. But that means work.
