here's some sites (you didn't include your email address so I couldn't reply that way)

http://www.clearwaterbutterfly.com/page2.html

http://www.butterflybrilliance.com.au/butterfly_releases/release_methods.html


I found these on a google search - I am sure you can search for more info. I definitely suggest the mass release as the individual could yield too many dead butterflies (I think even one is too many).

Good luck!!!
