Another four Clouded Yellows over a four hour period (that's 37 different individuals this year). Today's butterflies photographed and checked, as different individuals. Right now, each one remains in the garden for 3-5 minutes, and then continues heading south. Most interesting record was a Brown Argus egg-laying on Round-leaved Cranesbill. These tiny plants are only showing two leaves. It's the first time I have seen this.
