Butterfly populations are a very good indicator of the health of an area's ecosystem !!

   The Golden Birdwing is a large butterfly that has a maximum wingspan ranging from 5 3/4 inches to 6 1/4 inches (4.9 to 16.0cm ), whereas the females have a wingspan is about 5 1/2 inches to 6 1/3 inches (14.2 to 16.2cm). The Wallace-s Golden Birdwing Butterfly can differ in size according to whether they are the summer generation, spring generation, or the autumn generation. The male Wallace-s Golden Birdwing Butterfly will travel a maximum distance of 2 1/2 miles (4 kilometers) from where they pupate, whereas the female ones will travel a maximum distance of 1 2/3 miles (3 kilometers) from where they pupate.
   During the hottest months, the Golden Birdwing butterflies fly from the month of September to April. At lower heights, the Golden Birdwing Butterfly come out between September and November months and then from January to March when humidity, temperatures and precipitation are high, and the days are extensive. Adult Golden butterflies are more copious from September to November and again from February to April, even though this differs somewhat between different areas. Though the Golden Birdwing Butterfly have two breeding periods at lower heights, there is only a single breeding at higher altitudes.
