Great Mormon

Papilio memnon

Great Mormon butterflies glide through southern Asian canopy gaps and citrus groves on strikingly large wings. Males feature dark velvety black upperwings streaked with subtle blue, while females display dramatic polymorphism with dozens of distinct color forms mimicking toxic swallowtails. Caterpillars disguise themselves as fresh bird droppings before maturing into smooth green larvae on Rutaceae foliage.

Responsible observation
  • Spotting Females: Look for varied wing patterns, as females mimic several toxic swallowtails to deter predators.
  • Finding Caterpillars: Check young shoots of citrus trees for bird dropping mimicking early instars.
  • Mud Puddling: Watch damp soil or riverbanks where males gather to absorb essential minerals and salts.
