France is, comparing to the Netherlands, a huge country with rough nature and a lot of national parks. Beyond that it is a paradise for nature (butterfly) photographers AND......they have good wine, croissants and cheese!
I really love France, especially the southern regions like the Ardeche, Cevennes, Dordogne, Drome, Tarn, Vercors, they have rough nature and the weather is good. Good weather = a lot of butterflies.
In France there are a lot of butterfly species and subspecies (about 240!) and I never have to search long to find a beautiful butterfly. Photographing them sometimes is a real challenge as the temperatures are often high (even early in the morning), the light is too hard or the butterflies are not doing what I wont. The Large Blue by example, they noticed me every time and were not be willing opening their wings :-(.
