Hi Pixelated ,
Apologies for the late reply , missed it till just now!:embrass:
Thank you for dropping by and show interest and concern on the progress of the Harlequin!
From my record they have survived and successfully propagate on-site for up to 17 months after released .
On 18th June 2009 2 adults were sighted and recorded, this was 17 months after the last release on early January 2008. With their life span ( from egg to adult to natural death) of approx.40 days . These two individuals would have being at least the 13th Generation of those released on January 2008.
With the additional reinforcement carried out on November to December 2009 by Hortpark nursery and myself, these would further enhance their chances of survival, and standing on the new site.
Regular visits are still being make on the release site, but it is difficult to spot and monitor them in the wild . Basing on actual sighting we have experienced it is likely they are doing fine quietly on site .
We are quite confident that someone will encounter them on site from now till mid 2011 and hopefully for many more years to come.
Cheers!
