Green Dragontail (Lamproptera Meges)


Green Dragontail Butterfly

Belonging to the family of swallowtail butterfly, the Green Dragontail is indigenous to South and Southeast Asia. This butterfly has ten identified subspecies, most of which are found in and around the Java, Sumatra, Sulawesi and Borneo regions.

Scientific Classification

  • Family: Papilionidae
  • Genus: Lamproptera
  • Scientific Name: Lamproptera meges

Description and Identification


The caterpillar has a dark green body spotted in black.


The chrysalis or pupa is stuck to a leaf’s upper surface by its cremaster (hook-like tip).

Adult Butterfly

Sexual Dimorphism: Present

Color and Appearance: A black and white color pattern runs throughout their body. When the wings are open, their bodies are black in color, with a light green band observed on their upper hind wing (as opposed to the White Dragontail, which has white wings), prominent mostly at the time of their flight. When the wings are closed, the color remains the same, i.e., black due to the presence of transparent windows. The females have a dull appearance, with grooves located on their ventral plate just above their abdominal tip to help in copulation. The males, on the other hand, lack the sex mark through which they could be more distinctly identified.

The Tail: The wings of the Green Dragontail extend to form a long black tail, tipped in white with a length of 25-40 mm (0.98-1.57 in).  Their long tail serves as a rudder when in motion, moving back and forth at a rapid pace just like dragonflies.
