white and undulate stripes running across from costal
margin to hind margin plus a shorter one from R2-M3 region;
besides, four stripes situated within discoidal cell;
underside of forewing similar to upperside but paler in
colouration; hindwing ground colour black and with similar

Distribution
This species is widely ranging from N.E. India, Yuennan,
N. Thailand, Burma and Bhutan. Some authors have proposed
several subspecies for this species. Since we have not
found significant differences between them, we follow
the opinion of Munoz & Corrochano (2000) to treat
all of them into one single species. |

Habitat and Ecology
According to Igarashi & Fukuda (1997), this species
is univoltine and the adults fly in August to September.
The adults usually fly slowly and elegantly or soar above
canopy layer in cloudy weather. The confirmed nectar sources
are Umbelliferae and Polygonaceae. Oviposition occurs
in middle September to Octobre. Females lay eggs in group
under leaves of hostplants. In the Chasilahka area of
N. Bhutan, this species utilizes Aristolochia griffithii
as hostplant while the larvae could be bred with other
species of Aristolochia. Larval colouration is black with
numerous verrucae on trunk. Pupation occurs in fallen
leaves. |

Threats and Conservation Status
Habitat destruction and over-collecting have been the
main threats to this rare species. Besides the CITES convention,
European Union, this species is as well protected by India
and China (New & Collins, 1991). |
