A Rabble of Puddlers

Recently, we were coming from the garden on one of the dirt roads where  small springs seep and run down the hill, creating spots that stay pretty wet, except during droughts. Ahead of the truck, we could not help but notice a large group of cloudless sulphur butterflies with a few others gathered in one small, wet spot. I knew that the purpose of puddling is to obtain nutrients not found in flower nectar and I have just read that with many species of butterflies, it is  only the males that do this. The nutrients are then presented to the females as gifts during mating.

I also just learned that the collective for butterflies is rabble, and also a flight. Rabble sounds right for here.
