A small sandbank not far from the pier of Fazenda San Fransico was crowded with a great number of butterflies, and I was fortunate to disembark and get some shots, but not long enough as I was “disturbed” by the appearance of giant otters on the other side of the river.
Also called venusta grass yellow.
Thanks to Kim Garwood for identification.
Garwood adds: “Usually it is mostly males in puddle parties like this. The females don’t need to get the minerals from the wet sand like the males do, so you rarely see females in these big groups.”
