When is the flying period of the Richmond Birdwing Butterfly?
In the warmer months the butterflies fly from September to April. At lower altitudes, the adult butterflies emerge between September and November and then from January-March when temperatures, humidity, and rainfall are high, and the days are long. Adults are most abundant from September – November and again February – April, although this varies slightly between different regions. While there are two breeding periods at lower altitudes, there is only one at higher altitudes.
