HortNews is reporting that forestry researchers in New Zealand are seeking permission to import Cleopus japonicus, a weevil that defoliates the invasive butterfly bush (Buddleja davidii, sometimes known horticulturally as Buddleia). This is in spite of the fact that evidence has shown that the weevils also feed on some of the other species in the genus that are present in New Zealand, albeit non-native. Butterfly bush is quite popular among gardeners worldwide, with many cultivars showcasing an array of brilliantly-colored flowers. The weevil in question, native to Asia, has also been shown to attack native hebes (Hebe spp.) species, but scientists believe the negative impacts of the butterfly bush invasion outweigh the potential weevil risk to native plant species.

Thank you for linking to the Hebe Society.
Please note that your link at http://invasivespecies.blogspot.com/2003_12_01_archive.html is out of date. Would you change it to point to www.hebesoc.org.
The old Hebe Society website at www.hebesoc.vispa.com will be maintained to the end of 2009, then will cease operating.
Thank you for your co-operation
Best wishes for 2009
Tony Hayter (Secretary)
Done.
