On a trip to the Westminster Butterfly Pavilion a few weeks back, we saw this interesting crowd on a cluster of branches:
I’m not sure why it was such prime real estate for the little critters, but they were all putting in a good effort to chase their neighbors off the twigs. At any one time, at most 4 butterflies were on the branches while 3 or 4 were hovering nearby, trying to take their places.
That is a super group portrait. Nice variety of colours.
