A. We ship live
butterflies using FED EX priority overnight Shipping.  Live butterflies
are placed in glassine envelopes, and then put comfortably in a softly padded
box.  That box is then placed in an insulated cooler box with an ice pack,
so that the butterflies stay cool and comfortable for their trip.  Live
butterflies must be kept cool until about one hour before the release.
This keeps them calm and healthy in a dormant type state.
