Ron, perhaps I wasn't clear. What I was saying was that I
didn't think theft of butterflies from overwintering site, transferred
to U.S. buyers was feasible, for many reasons - not just
the inability to preserve livestock effectively by cooling them.
Of course, butterfly breeders use temperature to regulate
development (caterpillars and chrysalides, increase warmth
to speed development and emergence or cool down to slow
development). Adult butterflies are often containerized and cooled
to lengthen their lifespan, removing and feeding them at
certain intervals.
I had a hard time picturing the butterfly bandits gently
removing the butterflies from their containers and hand
feeding them, at the correct intervals, to prevent dehydration
and give them nourishment. Selling drugs would be
a lot easier and more lucrative if one were choosing which
illegal activity to take part in.
If anyone is interested, I would be glad to forward a
temperature chart for controlling livestock growth
for Monarchs, Painted Lady, Mourning Cloak,
Red Admiral, Black Swallowtail, Giant Swallowtail,
Zebras and Gulf Fritillaries, attached to private
e-mail.
