Pat, at no time on this list have you ever explained to us
what you think are the "important dangers" involved with
the interstate transport and release of monarch butterflies or
painted ladies - the two species that are used for nearly all
commercial releases. 

We would love to hear your ideas, from both a theoretical
standpoint and from actual case histories that you might be aware
involving these or other migratory insect species with worldwide
distributions.

Best regards,
