another fabulous planthopper from Costa Rica, Biolleyana costalis. juveniles are colorful, with a plume of shiny blue wax filaments on their tails.
later in life they will adopt a different, more modest color scheme in exchange for elaborately veined wings. a hint of the old self remains—a tiny orange crescent on each forewing matching the markings on juveniles’ wing buds.
Found throughout the eastern United States and down into Mexico, this species, like other bristle flies, is a protelean parasitoid with primarily true bug hosts. Adults feed on flower nectar, true bug honeydew, and pollen.
