Pat, I wrote: "No outbreaks of any infectious diseases have been
known to occur in wild populations of the monarch butterfly."
By this I mean the large annual fluctuations in monarch
populations have never been linked to any infectious diseases.

As I stated in my earlier post, this was decided several years ago
by the US Federal Government:
The Monarch, Painted Lady, Red Admiral, Buckeye, Giant
Swallowtail, Black Swallowtail, Gulf Fritillary, Zebra
(Heliconian), and Mourning Cloak may be released in any of
the 48 states where these species naturally range.
Monarchs and painted ladies account for nearly all releases. The
other species are either too fragile to withstand overnight shipping
and handling (as adults) or they are too difficult to rear
economically in any quantity. In fact, only one company ships
Painted Ladies in large quantities and only as larvae and pupae.
