Highlights:
Fresh Monarchs — and a Monarch in Wisconsin!
Look
at the odd map! A narrow string of sightings stretches across
Illinois all the way to central Wisconsin. An early monarch was
spotted at latitude 44N in Wisconsin on April 20th. How early
is this monarch and why is it so far ahead of other Midwest sightings?
Check it out...>>
Old
monarchs with well-worn wings were still being seen last week.
People reported them from these five states: MS, OK, KS, IL, VA,
and MD. But sightings of fresh-winged butterflies mean that the
new monarch generation has arrived.
"Our
first adults have now emerged from the chrysalis stage and are
on the wing," wrote Bill Stark from Clinton, MS on April
25. "These adults appeared 32 days after the eggs were deposited."
>>
Just think: New butterflies are appearing every day in places
where monarchs laid their eggs a month ago (see
March 30 map). Watch for the number of sightings to climb
in the weeks ahead as the population builds.

You
can add four new states to your Prediction
Chart today. When do you think the first monarch will be
reported from a Canadian province? Which province do you suppose
it will be?
- Look
back at the season thus far: How are the warm March temperatures
and
April cold snap related to the migration pattern we see today?

How Early is the Wisconsin
Monarch? |
A
monarch in Wisconsin on April 20th? How unusual is this?
Dig into
data from past years. (See
maps 1997 - 2007.) Then explain why this sighting is remarkable. In
your answer include at least one measurement and one comparison.
- Write
your answer in your Monarch Butterfly Migration Journal. >>

Slideshow:
Butterfly Wings: Take a Close Look! >> |
Monarch wings are strong. They can carry a monarch over a thousand of
miles. They can last over a hundred years if they're kept in a museum.
But life is tough for a butterfly. Wings that begin as fresh as a flower,
become faded, tattered, and torn over time. You can learn a lot about
a butterfly by looking closely at its wings. Take a look!
