The past few days the meadow has just been overflowing with tiny butterflies, especially little orange-brown skippers. They rise in clouds when I walk, especially around the patches of trefoil, vetch and (in the garden) valerian. I can't get over how many there are, probably thousands on our 2 acres alone.
I just realized that by coincidence all five of these photos were taken on the valerian flowers in our garden. Valerian in your garden turns out to be great for attracting butterflies and moths, as well as being very fragrant.
