They lay their eggs on the underside of the Passiflora plants. The larva that emerge are pale green with red spines on their backs and sides. The larva create a pupae that resembles a bird dropping, a strong contrast to related species that create pupa that look like leaves. The pupa is brown with gray spots.
Female Scarce Bamboo Page Butterfly remain in the canopy unless descending to drink from Passiflora plants. Males are much more elusive and wide ranging.

The Scarce Bamboo Page Butterfly are common in their range, but they are rarely seen by visitors because they remain in the forest canopy most of the time. Many butterfly watchers mistake Siproeta stelenes for the Scarce Bamboo Page Butterfly species, mostly because Siproeta are found around forest clearings and the edges of the forest at heights of up to two meters. The biggest difference between the two to the casual observer is the different shapes of the wings. However, they both do overlap in range in the northern Amazon. However, the Siproeta stelenes ranges farther north, even to Mexico.
The Scarce Bamboo Page or Dido Longwing Butterfly lives in wet tropical forests at altitudes from sea level to 3000 feet (914 meters). They are not found in rain forests at higher altitudes or deciduous forests at any altitude.
The Scarce Bamboo Page Butterfly have rapid flight, but they are very agile.
