The Sara Longwing Butterfly, also called the Small Blue Grecian, one of the Heliconian family, is native to Mexico through to northern South America.
The topside has a beautiful midnight blue iridescence on black, not seen from all angles. Male and female have a similar appearance.
In common with other Heliconian butterflies, adults not only drink nectar but also eat pollen which improves their lifespan.
Caterpillars eat Passion Flower vines, the toxins from which give them and the adult butterflies some protection from predators.
One subspecies of the Sara Longwing, H. s. theudela native to Costa Rica, has a white keyboard bar
bordering its hindwings.
