Aristolochia elegans - Dutchman's Pipe - and its impact on the Richmond Birdwing Butterfly

I was sent a well informed and considerate message by one of our ebay customers this morning about one of our listings - Aristolochia elegans - Dutchman's Pipe. It is an introduced species that has become a garden escapee if not contained well so I knew of it's ability to become weedy in some areas hence not being sold to the Northern Territitory or Western Australia but I was unaware of its impact on the Richmond Birdwing Butterfly.

Once I read up on this issue, I immediately pulled the listing on our ebay store because I won't no part in adding to any detrimental environmental impacts especially in my local area.
