I have uploaded the pictures to my photobucket album. In all, 20 (+1 or +2) species spotted in one cool morning. Overhead a conversation that this weather is typical of Autumn instead of Winter.

Spotted the metallic blue upperside of an Arhopala spp. while the TV crew was filming, so did not take a snap. Also, spotted possibly a Common Hedge Blue along the stream.

At least two or more species could have been among the flock.
