Also known as Small Postman, Red Passion Flower Butterfly, Crimson-patched Longwing
Red postman butterflies patrol predictable forest trap-lines each morning to gather both nectar and protein-rich pollen, an unusual adaptation that fuels their remarkably long multi-month lifespans. Individuals roost communally at dusk on favored twigs or hanging tendrils, returning to the exact same perch night after night using keen spatial memory. They represent one of nature's classic examples of Müllerian mimicry, sharing nearly identical warning patterns and cyanogenic toxins with their close co-mimic, the postman butterfly.
