Recently described (1965), and with a very limited distribution, chikae is known only from N Luzon in the Philippines. It prefers forests above 1500 meters on the peaks and western slopes of the Cordillera central (Mt St. Thomas, areas around Bontoc and Baguio, the latter of which is a popular Summer resort area for the Japanese) and readily visits flowers.

hermeli, found only on N Mindoro, is quite similar though with more
red on the hindwings of the males and a rather spectacular amount of red
on the females. It is currently ranked as a full species, but may turn
out to be a subspecies of
chikae, extending chikae's range
to two Philippine islands. The two can be distinguished by the width of
the tails: chikae has more spatulate tails, while those of hermelae are
