Two pairs of black & yellow swallowtail and buttery-yellow pieridae butterflies arrayed on a diagonal section of rusty-orange waterfall spillway. Located at the Chaloyacu River in Ecuador.

Dance of the #butterflies. Around a small waterfall splashing into the #Chaloyacu River in #Ecuador, multispecies groups of #swallowtail & #Pieridae butterflies jockeyed for position around some slimy protrusions from the slick spillway. A spectacularly beautiful display of fluttering prowess.
