Maolin's Butterfly watching route

Maolin's Butterfly watching route
There are two species of winter migrating butterflies in the world, the Mexican Monarch Butterflies and the Taiwanese Purple Crow Butterflies (Euploea tulliolus).

Taiwan’s Purple Crow Butterflies are subtropical butterflies, and live within gorges that are located less than 500 meters above sea level. As long as the weather is right, rainless and sunny, they are active from morning to night every day. They follow their “Three No’s Policy” strictly: No checking in, No being late, and no taking leave. Thus, in contrast, the viewing of Taiwan’s Purple Crow Butterflies is relatively easier, more rewarding and very interesting.

The best time to go butterfly watching.
The best season to watch butterflies is between November and March. The first flocks of butterflies arrive around November, and gradually increase in number. After February the numbers gradually dwindle as some will die from courtship and mating, or some others will migrate. Thus, the peak of the butterfly season is from December to February, which also corresponds to the local Chinese date harvest period. Visitors can arrange for a tour that includes both butterfly watching and experiencing the Chinese date harvest!

Eight-thirty a.m. to eleven a.m. is the best period of time to go butterfly watching.
The most ideal situation is the day after a rainfall, when the sun is shining brightly. If visitors are lucky, and the time and place are all perfect, masses of Purple Crow Butterflies can be seen gliding down through the gorge, preparing to feed, drink, and sunbathe. As visitors watch their elegant appearance as they search for flowers and drinking nectar, it becomes clear why people refer to these butterflies as the dancers of nature. Obviously, it will take some luck to be able to see all of this in one day!
