Update :

Around 60 Harlequins eclosed in the last few days .

These are housed in the breeding cages. I am keeping my fingers crossed that they will mate and lay us more eggs for Phase II of the project.

A local environmentally-friendly organization roped in to collaborate with ButterflyCircle in this conservation project, was supplied and reinforced from our stock of eggs, caterpillars and pupae . These are doing fine in their hands, this collaboration is to spread the risk and also as an alternative breeding source for this project.

Thank You Peng Eik,

Here are a few shots of approx. 60 males and females Harlequins that were raised from the eggs laid by 12 of the evacuees , some of them have started ovipositing in the last 24 hours.

More details of the Project can be found here at Butterflies of Singapore Blog

First Release:

A video clip , sharing the magical moment of a Harlequin eclosing from its pupa under the tender loving care of ButterflyCircle.

A first batch of 22 pupae, ready to eclose within 12 hours were deposited at one of the planned release site (Site A) two weeks ago and all 22 pupae subsequently eclosed successfully unattended . 4 adults were sighted a few days later during a site check. We are keeping our fingers crossed that they had mated and laid eggs on the host plant on the site.

The fact that it is only extant in a small areas where we found them suggested to us that it has an unique set of conditions that allow it to thrive. we have selected the release sites very carefully, other than the present of the host plant, the level of humidity , shades and undergrowth were also taken into consideration.

The rationale to place some pupae to eclose naturally is part of the risk management module of the project. It also serves as a pre-release trial, to ascertain the butterfly's ability to adapt to the new site, prior to the mass introduction in Phrase II.

An Update

A few hundred Harlequin caterpillars are into the 3rd-4th instars.

If all goes well, we will be carrying out the mass release of the Butterflies unto selected sites in the next couple of weeks.

The above Save the Harlequin Project has been sanctioned by NPark's Biodiversity Centre / Conservation Division.

The first Mass Release of Harlequin pupae was carried out today on 2 sites , a total of 200+ pupae are in the wild .These pupae should eclosed within the next 48 hours, and it will be up to Mr and Mrs Harlequin to propagate naturally on these 2 sites. More Mass releases have been planned and will be conducted on other selected sites in the coming months.

This conclude the main part of our first attempt in ex situ butterfly conservation which stretched over a period of 20 months: From hostplant identification, monitoring of population statistic, habitat monitoring/observation, selection of new habitat , collection of adults, harvesting of eggs, mass breeding risk management , the caring and breeding from eggs to pupae/ butterfly in a mass scale. With the conclusion of this part of the project we are now better equipped in future for in situ or ex situ butterfly conservation.

We will be moving to the follow up plan which comprises of regular visits to check how they fair in these new habitats, and where necessary and practical to reinforce their presence on these sites.
