Clearwing Swallowtail Butterfly is the medium size swallowtail butterfly. The male and female look very different. Female is pale brown in colour, with scales on wings lost and become clear. The abdomen is black with orange colour between segments. Male is more colourful, with black dots on front clear wings. The hind wings are red, black and white in colour. The abdomen is red on black, the strong warning colours.

Males and females behave very differently as well. Males always fly non-stop during the sunny day. They fly about 2 meters above ground, patrolling their territory about a 100 meters long.

Finally, we found a male rested on low plants and we took some photos.

On a Dec 2009 morning, the weather was not very good but still there was the sunshine. In the Anstead Forest we saw occasionally some male Clearwing Swallowtail Butterflies flying around. Suddenly it started raining and the temperature dropped by a few degree. We understood that the butterflies should stop flying and we looked around and tried to found any of them. Then we saw a male Clearwing Swallowtail rested on grass near the ground. It flied away for a short distance when we came closer. Anyway, we managed to took a few photos.

Females are always found flying very close to the ground, looking for host plants to lay eggs.

In Anstead Forest Reserve near the hill top, there were always those Clearwing Swallowtail Butterflies during the summer season. However, they seldom rest so we had not taken any of their good pictures yet. Above pictures were taken on Feb 2009.
