I understand Urquhart claims there
is crossing over of the two
populations via the Snake River. What
genetic evidence is there regarding
the similarities or dissimilarities of
the eastern population of monarchs
versus the western population of
monarchs? Have any DNA tests been done
on the two separate populations? If
so, by whom and when were the data
published? Do you believe the two
populations are on the path to
speciation? (Mon, 11 Dec 2000) |

Answer |
The latest we have heard regarding
the Monarchs indicates very slight
differences between western and
eastern populations, genetically
speaking. Dr. Andrew Brower at the
University of Oregon has done some
work on thier genetics. If you check
his web site and list of publications
you should be able to find a paper
that answers your questions.
Personally, we think it is likey that
there will always be some mixing of
the two populations during their
summer generations in the Rockies. And
that these differences will remain
minor as long as a mixing zone
exists.... |

i was wondering if you could help
me? i was directed here by Mr.
Sperling. i am going to raise monarch
butteflies this summer and have been
searching for a better way to feed the
larvae instead of using milkweed. I
have heard and seen a mushy substance
that was milkweed "goo"
looked like lab food if you ask me. I
was wondering if you have ever heard
of or seen this stuff. if you know of
this goo or can help me find a
different way to feed the larvae then
the plant that would be a great help
to me. (Tue, 16 Jan 2001) |

Answer |
While none of us has direct
experience rearing monarchs on diet
(the mushy stuff), it may exist. Your
best bet would be to contact Carolina
Biological supply, or some other
biological supply company and ask them
about an artificial medium for
monarchs. |
